Details of the p146f OBD Code
P146F code indicates an issue with the oil pressure control solenoid circuit in the engine.
OBD code P146F means that a fault has been detected in the exhaust gas recirculation (EGR) cooler bypass control circuit.
This code is triggered by the engine control module (ECM) when it detects a problem with the EGR cooler bypass control circuit.
The EGR cooler bypass control circuit is responsible for regulating the flow of exhaust gases through the EGR cooler to help reduce emissions.
When this circuit malfunctions, it can affect the performance and emissions of the vehicle.
Mechanic’s Tech Notes
This code indicates a fault with the oil pressure control solenoid in the engine.
OBDII code P146F relates to an issue with the transmission control module (TCM).
To diagnose this, check TCM power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
This thorough inspection can help pinpoint the root cause of the problem.
