Details of the p014c OBD Code
P014C code indicates a fault in the fuel delivery system’s pressure control.
OBD code P014C means the O2 Sensor Delayed Response Lean to Rich Bank 1 Sensor 1. This code is triggered when the oxygen sensor (Bank 1 Sensor 1) takes too long to respond to changes in the airfuel mixture, specifically from lean to rich.
The ECM monitors the signal from this oxygen sensor to adjust fuel delivery for optimal combustion efficiency.
Mechanic’s Tech Notes
This code indicates a problem with the fuel injector group B circuit low.
OBDII code P014C relates to the transmission control module (TCM) not responding properly.
To diagnose, 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 wiring harnesses and connectors for damage, and check for broken, bent, or corroded pins.
This thorough inspection can help pinpoint the issue and guide you towards an effective repair.
