High fuel prices make this new oxygen tester a must buy! If you want to make money while saving your customers money these new oxygen sensor testers are for you. This new oxygen sensor tester is a money making machine for automotive technicians and shops. It tests all types of oxygen sensors to make sure that they are working. Some refer to the PRO2 as an oxygen sensor tester, while others refer to it as an oxygen sensor analyzer, or oxygen monitor, or oxygen sensor diagnostics equipment. In Europe oxygen sensors are known as lambda sensors, so this oxygen sensor tester is known as a lambda sensor tester. It doesn’t matter what you call your O2 sensor tester as long as it makes you money and keeps your customers satisfied. So let’s begin to explain how you use this oxygen sensor tester to make money and make your customers love you, both at the same time.
4 Steps To Make Money Using The Pro2 Oxygen Sensor Tester While Saving Your Customers Money:
- O2 sensors will start to degrade over time due to many factors. When this occurs, an engine warning light often does not come on to indicate a problem even though the O2 sensor is performing poorly. There is no warning light because the vehicle manufacturers (OEMs) have set the parameters very loosely before a “trigger” occurs. This means that the vehicle can be operating really far from optimally and no warning light will come on.
- When an O2 sensor is not operating at peak efficiency, fuel consumption will suffer by upwards of 10% to 15%.
- If you want to find a problem with an oxygen sensor, this O2 sensor tester is for you. With the Pro2, an O2 sensor can be definitively proven within minutes to be O.K. or operating below peak performance. Vehicles are supposed to burn fuel optimally at the stoichiometric ratio of 14.7:1. This is the optimal air to fuel ratio. Faulty oxygen sensors ruin fuel consumption. Use the Pro2 for quick oxygen sensor trouble shooting.
- Change the O2 sensor and provide a high return on the investment to the driver through reduced fuel costs. Build a new profit center for yourself in providing this preventive maintenance service while increasing your sales of oxygen sensors. At the same time, your customer satisfaction ratings will soar when you cut their fuel costs. Customers love it when you can reduce fuel consumption especially at these times of really high gas prices. Remember: reduce fuel consumption = fuel savings = happy customers.
Why Buy A Pro2 Oxygen Sensor Tester?
- 100% certainty on most oxygen sensor diagnostics – no more guessing
- Measure payback times in weeks if used appropriately
- Easy to use & very quick – just minutes to know if the O2 sensor is good or not
- Until the Pro2, there has been no quick, easy, accurate and low cost diagnostic tester to check an O2 sensor. Scan tools, oscilloscopes (scopes), OBD II code readers, multimeters & voltmeters cannot get the job done right and / or quickly. Many excellent technicians think that they can find a faulty oxygen sensor with some OBDII equipment. Find out elsewhere on this site why it is not possible to prove that you have a bad oxygen sensor with an OBD II tester. You need the Pro2 to find oxygen sensor problems.
- Works on the following types of oxygen sensors: titanium sensors (also referred to as titania sensors), zirconium sensors (also referred to as zirconia sensors), single wire sensors, 2 wire sensors, 3 wire sensors, 4 wire sensors, heated sensors and unheated sensors
A Large percentage of O2 Sensors Should Be Changed to Improve Fuel Consumption. A study conducted by Sierra Research in 1996 found a high percentage of vehicles that fail enhanced I/M 240 emissions tests failed due to a bad oxygen sensor. Failure rates were highest on older vehicles with unheated O2 sensors (from 60% to 72%). The next highest failure rate was among vehicles with first generation heated O2 sensors (19% to 27%), and the lowest failures were found on the newest vehicles with second generation heated O2 sensors (2% to 14%). The study found that replacing the O2 sensor, on average, reduced hydrocarbon (HC) emissions by 23% and carbon monoxide (CO) emissions by 3%. The U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) found that oxygen sensor replacement was required on 42%-58% of all vehicles found emitting high levels of hydrocarbons (HC) or carbon monoxide (CO) during an emissions check. This makes checking the operation of the oxygen sensor a priority anytime a vehicle fails an emissions test due to high HC or CO. So if your state conducts emissions testing or emissions certification, these O2 sensor testers can be used as a preventive maintenance tool for pre-testing check ups or for post-testing oxygen sensor diagnostics. Either way use your emissions laws not only to protect the environment but also to legitimately make money at the same time.
Pro2 Benefits To The Shop Owner / Technician:
- Reduction in service time. The Pro2 gives a definitive result in minutes. The Pro2 may save an hour of high-priced labor versus OEM full diagnostics stations or scan tools. When you’re dealing with drivability issues & need to move on to engine tuning, your customers are not interested while you’re still trying to figure out what OBD trouble codes mean.
- Reduction in service misdiagnoses. There are currently no other full-proof methods of testing O2 sensors, resulting in many erroneous service procedures
- Reduction in warranty costs. Many perfectly functioning sensors are replaced because no accurate, convenient, low-cost tester exists, resulting in comebacks & unsatisfied customers
- Minimal training or experience required. This menu-driven product is very easy to use. Other diagnostics methods require great skill and often expensive equipment
- Easy hook-up. Uses a non-invasive method with no need to disconnect sensors or break lines
- Frees up bay time. Use anywhere, any time. No need for a lift, pit or under-vehicle access
- Works on a wide array of O2 sensors including a titanium sensor, a zirconium sensor, a heated sensor & an unheated sensor

- Longer catalytic converter life
Why You Can’t Rely On Scan Tools, OEM Diagnostic Stations, Oscilloscopes, Multimeters & Code Readers To Definitively Diagnose An O2 Sensor Problem:
Many shop owners and technicians are under the mistaken belief that their current automotive test equipment will take care of diagnosing faulty O2 sensors in a timely and cost-effective manner. Usually equipment will indicate an O2 sensor problem but it will not definitively tell the technician if the sensor is good or bad – it just indicates whether or not the sensor is operating within parameters. Using many of these automotive testers requires much experience and training and can be very time consuming.
Failure To Isolate O2 Sensor From Rest Of Engine Management System
The problem with most emissions diagnostics is this: the automotive diagnostic equipment does not isolate the O2 sensor from the rest of the engine management system (EMS). So when an O2 sensor seems to be “bad” it may actually be a good sensor which is reading an incorrect fuel mixture caused by inputs from other sources, these other sources being the real cause of the problem. The O2 sensor’s output goes to the engine management system (EMS). The engine management system is also known as the engine control module or ECM. The EMS, amongst other systems, regulates ignition and fuel injection into the engine.
The EMS also receives inputs from the mass airflow sensor, the throttle position sensor, and other sources. Any of these sources can cause the exhaust gas to be too rich or lean. Faulty readings can also occur because of poor wiring, termination, or other hardware or software problems. For example, a scan tool or scope may well indicate (with diagnostic trouble codes or DTC in the case of the scan tool) that a sensor is measuring rich or lean but this reading could be obtained from a perfectly good oxygen sensor. The level of oxygen may indicate rich fuel or lean fuel because of causes other than a faulty oxygen sensor such as from a cracked manifold, which would indicate too much oxygen after engine burn.
Problems With Breaking Into A Line To Test An O2 Sensor:
Most equipment requires an invasive method of diagnostics involving disconnecting circuit connectors to gain access to voltage / frequency readings. This introduces accessibility and corrosion problems while making a sensor connection. Many connections may be brittle due to age and degraded from salt, oil, dirt and heat. Assembly and disassembly risks damage to the socket (interlocks) and possible introduction of resistance / arcing once re-assembled.
Problems With Using Fault Code Readers & Warning Lights:
Most O2 diagnostics begin when a driver experiences engine problems or the malfunction indication light (MIL) or engine warning light comes on at the dashboard. A fault code reader (showing diagnostics trouble codes or DTCs) may indicate an O2 sensor warning / emissions warning, which may have nothing to do with a faulty O2 sensor but may be caused by external factors. If there are multiple onboard diagnostics trouble codes (OBD II codes), this complicates diagnosis as each code may have multiple causes. Some technicians may take a chance and change the oxygen sensor right away hoping that indeed the sensor is faulty. After an emissions service or emissions repair is performed, the OBDII fault code needs to be wiped from the vehicle control module memory to extinguish the MIL. The problem with this is that the technician and driver both think that the problem is solved, when it may in fact not be. It takes repetitive faults before the trouble code light appears again, and this usually take days to occur. Hence if a technician just changes an oxygen sensor, he will not know definitively that the problem has been solved and may well have a surprise return customer a week or so later.
Problems With Using Voltmeters & Multimeters:
One cannot check a sensor simply with a voltmeter or multi-meter. In addition to voltage, one needs the cycle time (frequency) as well as the peaks and troughs (amplitude). Furthermore, most multimeters are not accurate enough to measure the small voltages in question.
Problems With Using Oscilloscopes:
As described above, using a scope suffers all the drawbacks associated with not testing an O2 sensor in isolation and having to break into line to perform a test. Scopes are very expensive and require a high level of technical skill / training to interpret results.
Problems With Scan Tools & OEM Diagnostics Work Stations:
It may take over an hour to run a full diagnostics test to determine whether the O2 sensor is at fault. Even when this result is obtained it may be incorrect because scan tools do not isolate the O2 sensor from the influence of other factors affecting the EMS, as described above. This type of emissions diagnostics may well present many diagnostic routes for the technician to pursue. Use of high level diagnostic equipment is usually carried out in a dedicated diagnostics bay, where labor time is very expensive. If the OBD II diagnostics quickly resolves the fault a minimum charge of one hour would normally be attributed to the repair. The same hour in a normal repair bay would be far less expensive.
