Code P0298 Dodge Description

The Engine Oil Temperature (EOT) Sensor is a variable resistor that measures the temperature of the engine oil. The Powertrain Control Module (PCM) supplies a 5-Volt reference and a ground to the sensors low reference signal circuit. When the oil temperature is low, the sensor resistance is high. When the oil temperature is high, the sensor resistance is low. The Diagnostic Trouble Code (DTC) P0298 is set when the Engine oil temperature rises faster than a calibrated modeled temperature. When the actual oil temperature exceeds the high boundary of the calibrated modeled temperature for three minutes the fault is set. Two trip fault. Three good trips to turn off the MIL.

Code Tech Notes

On engines that are equipped with an oil temperature sensor, the Powertrain Control Module (PCM) reads oil temperature to determine if it is excessive. When an oil temperature sensor is not present, the PCM uses an oil algorithm to infer the actual temperature. Engine shutdown strategy function is the same on vehicles with and without oil temperature sensors.

There is a factory service bulletin for the following Dodge Models:
2011 Dodge Avenger
2011 Dodge Caravan
2011 Dodge Challenger
2011 Dodge Charger
2011 Dodge Journey
Dodge Factory Service Bulletin OBDII Code P0298

The bulletin recommends reprogramming the Powertrain Control Module (PCM).

What is the Cost to Diagnose the Code?
