Details of the p0167 OBD Code
P0167 code relates to the ECM detecting a low voltage condition in the glow plug circuit.
OBD code P0167 means that the ECM has detected a low voltage condition in the cruise control set switch circuit.
This code is triggered by the ECM when it receives a signal from the cruise control set switch that indicates a voltage lower than the specified threshold.
The cruise control set switch is the component that triggers this fault code.
It is a switch located on the steering wheel or stalk that allows the driver to set the desired speed for the cruise control system.
The signal or system involved in this fault code is the cruise control set switch circuit.
When the voltage from the cruise control set switch falls below the threshold set by the ECM, it triggers the P0167 fault code, indicating a potential issue with the cruise control set switch circuit.
Mechanic’s Tech Notes
Code P0167 relates to the ECM detecting an open circuit in the bank 2 sensor 3 heater circuit.
OBDII code P0167 relates to a problem with the TCM power circuit.
To diagnose, use a voltmeter to check power and ground connections to the TCM.
Verify TCM communication over the CAN network using a scan tool.
If the wiring harness or connectors appear damaged, inspect for broken, bent, or corroded pins.
Reflashing the TCM might be necessary to resolve the issue.
