Details of the Chrysler p0198 OBD Code
Chrysler code P0198 relates to engine oil temperature sensor high voltage.
Code P0198 for Chrysler vehicles indicates that the Engine Oil Temperature Sensor 1 Circuit High input has been detected.
This means that the signal voltage from the engine oil temperature sensor is higher than the normal operating range specified by the ECM.
The ECM triggers this code based on the input it receives from the engine oil temperature sensor, which is usually located near the oil filter housing or in the oil pan.
The engine oil temperature sensor is part of the engine management system and helps the ECM monitor the temperature of the engine oil for optimal performance and efficiency.
Mechanic’s Tech Notes
P0198 is a fault code related to engine oil temperature sensor high voltage in Chrysler vehicles.
To diagnose and fix OBDII code P0198 in a Chrysler vehicle, start by checking the transmission fluid temperature sensor circuit.
Use a voltmeter to test the sensor’s resistance and voltage.
Inspect the wiring harness and connectors for any damage or corrosion.
Ensure the sensor is securely connected.
If no issues are found, the problem may lie with the sensor itself, requiring replacement.
