Diagnostic testing is an incredibly useful tool for helping to detect issues in your INFINITI. It enables our technicians to identify problems quicker than ever before. This time saving can then be passed on to you in lower repair bills. As your INFINITI dealer, we want to tell you more about how it works and the types of issues it can help identify.
Computer and Sensors
Every important system in your INFINITI has a sensor connected to it. All the sensors are connected to your vehicle’s computer. The computer sends instructions to the sensors and receives data from the sensors. The sensor data is used by the computer to make decisions that allow your vehicle to perform optimally.
The sensors monitor the systems they’re connected to, and they can detect even minute changes in a system’s behavior. If a sensor identifies a problem, it informs your car’s computer. The computer logs the problem with an error code and then illuminates a warning light on your dash.
How Testing Works
As we’ve seen, the computer identifies and logs issues. We connect your computer to a diagnostic scanner that reads and displays the error codes logged by the computer. These numbers are checked against the error codes for your model and reveal the affected system and potential issues. With this information, our technicians can concentrate on repairing the problem.
Identifiable Problems
A diagnostic test can highlight numerous problems. Let’s look at some situations it can highlight that need repair.
Blocked Catalytic Converter
The catalytic converter plays a vital role in your car. Combustion produces numerous dangerous and toxic gases. These gases pass into the catalytic converter, which uses intense pressure, extreme heat, and chemical reactions to convert them into harmless gases and water.
Carbon is a byproduct of the conversion process, and it can build up and block the converter. If this happens, exhaust gases are forced back into the engine, where they can cause misfiring, stalling, or other problems. A diagnostic will reveal the blocked converter, and we can swiftly unblock it to fix this problem.
Oxygen Sensor Malfunction
Oxygen sensors monitor the oxygen in the engine. This information allows the computer to adjust the level of oxygen supplied for combustion. A damaged sensor can seriously impact engine performance, as your computer has to guess the amount of oxygen in the engine.
If the computer guesses wrong, your engine might not receive enough air. This produces a high fuel-to-air ratio and turns your engine fuel-rich. A fuel-rich engine uses more fuel and can damage the spark plugs, ignition coils, and other engine components. If a damaged oxygen sensor is identified, we’ll replace it, and your engine air-to-fuel ratio should return to normal.
