Chrysler O2 Sensor Questions
Where is the Chrysler O2 sensor fuse for Bank One?Typically a fuse is not used for Chrysler O2 sensor heaters. This sensor heater has a ground and the element is heated by a feed directly from the ASD relay. If the car is operating, the relay is functioning fine. A P0134 code will be set when the oxygen sensor signal remains at the center. This would indicate that the heater is working fine. The code is also an indication of a lazy sensor. Replacing the upstream Chrysler O2 sensor should address the problem.
Is the error code P0420 on a Chrysler Pacifica 350 due to a defective O2 sensor?The code P0420 is not related to the O2 sensor. A shop can diagnose if it is the catalytic convertor or the O2 sensor causing the problem and replace whichever one.
What could cause a replacement Chrysler O2 sensor to fail in five days?There may be no aftermarket oxygen sensor compatible with an NGC controller, therefore, by installing an aftermarket oxygen sensor on a Chrysler vehicle newer than 2002.5, with an NGC controller, can cause the check engine light to come on. First, try replacing the sensor with a Mopar part and then disconnect the battery. This clears the controller memory for both fuel adaptive and oxygen sensor heater’s characteristics.
How to remove the Chrysler O2 sensor on a 2001 Town and Country 3.3 engine?To obtain clear access to the upstream Chrysler O2 sensor, the battery and the battery tray need to be removed and the speed control servo needs to be unbolted and repositioned. The removal steps are as follows:
1. The battery should be removed
2. Next the battery tray should come out
3. Disconnect the speed control vacuum harness and the electrical connector from the servo
4. The speed control servo and bracket should then be removed and repositioned
5. A socket such as the “Snap-on” (R) YA8875 or equivalent should be used to remove the sensor.
What is causing code “P0158 Oxygen Sensor Circuit High Voltage” (Bank2, sensor 2) on a 2003 Chrysler Concorde.This code means the Chrysler O2 sensor needs replaced. It is rarely a wiring or a PCM issue.
