DTC P01BD-86 Engine Oil Temperature Sensor "B" Circuit Intermittent/Erratic - Signal invalid: Action
WARNING: This page is about a different variant/trim than selected.
- Vehicle Conditions to enable DTC Logging Strategy
- Ignition on, Engine running
- Prioritized Checks to Perform
- Refer to the appropriate system wiring diagrams and check the resistance values at the oil temperature sensor. At an ambient air temperature (23°C), resistance values measured between the two poles of the oil temperature sensor should be greater than 2100 Ohms. Visually inspect the oil temperature sensor connector(s) for signs of water ingress, and pins for damage and/or corrosion. If resistance values are not to specification and/or if the oil temperature sensor connector is damaged, install a new oil temperature sensor
- Inspect connectors for signs of water ingress, and pins for damage and/or corrosion
- Refer to the appropriate system wiring diagrams and check the oil temperature sensor circuit for
- Short circuit to ground
- Short circuit to power
- Open circuit
- High resistance - resistance should be less than 0.1 Ohm
- Signs of water ingress, pins damage and/or corrosion of harness connector(s)
- If harness resistance values are not to specification and/or if the harness connector(s) are damaged, repair or replace the harness as required
- Visually inspect the oil temperature sensor circuit connector(s) at the powertrain control module for signs of water ingress, and pins for damage and/or corrosion. If the connector is damaged on the powertrain control module, install a new powertrain control module as required
- Using the Jaguar Land Rover approved diagnostic equipment, clear all stored Diagnostic Trouble Code(s) and retest
