Where to reset the computer on a Chrysler Town and Country?
Make sure you reset the computer only after you have finished repairing or servicing the car or you may risk damaging the computer. Locate the OBD port, which is the same size and shape as the scan tool’s connective end; the port can be found on the underside of the driver’s-side dash next to the steering column.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
Is there a way to reset the engine control module?
There are a few ways to reset your Engine control modules. One way is by disconnecting the battery cable for 2 to 3 minutes and waiting to see if the check engine light comes back on upon reconnecting the battery and start the car.
How does the O2 sensor in a car work?
The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle’s computer.
Why does my oxygen sensor stay in not ready mode?
If you have performed the necessary driver cycles and have not lost battery voltage or reset the computer at any time then you either have a problem with the heater circuit of the sensor or the computer is failing. I usually test the heater circuit first as it will not set a code if it is working, but just not reaching the right temperature.
Why does my oxygen sensor heater not set a code?
I usually test the heater circuit first as it will not set a code if it is working, but just not reaching the right temperature. Keep in mind that this does take quite a few drive cycles to complete. If the circuit is fine then the computer should be reflashed and then replaced if it does not take care of it.
