Description for Buick p1467
The fault code P1467 in a Buick relates to the AC compressor control circuit.
Code P1467 for a Buick indicates an issue with the AC pressure sensor circuit voltage being too low.
This fault code is triggered by the Engine Control Module (ECM) when it detects that the voltage from the AC pressure sensor is outside of the expected range.
The AC pressure sensor is part of the AC system and is responsible for monitoring the pressure of the refrigerant in the system.
When the sensor detects a voltage that is too low, it can indicate a problem with the sensor itself, the wiring, or the AC system’s pressure levels.
That fault code is a turning point. If repair costs are climbing and your current loan feels like it’s holding you back, this is the time to plan ahead. The free Car Loan Payment Tracker helps you see how quickly you can pay off what’s left—and start preparing, with confidence, for your dream car.
Tech Notes for Buick p1467
For Buick fault code P1467, check the AC refrigerant pressure sensor circuit for issues.
Fault code P1467 in a Buick typically indicates an issue with the AC compressor clutch control circuit.
To diagnose this, you can start by visually inspecting the wiring harness and connectors related to the AC compressor clutch.
Look for any visible damage, corrosion, or loose connections.
Next, you can use a multimeter to check the power and ground connections to the AC compressor clutch.
Ensure that there is power reaching the clutch when it should be engaged.
If there is no power, you may need to trace the circuit back to find the source of the issue.
Additionally, using a scan tool, you can monitor the signals going to and from the Transmission Control Module (TCM) related to the AC compressor clutch.
This can help you determine if the TCM is sending the correct signals for clutch engagement.
If all wiring and connections check out, and the TCM is functioning correctly, you may need to consider reprogramming or reflashing the TCM to address any softwarerelated issues that could be causing the fault code P1467.
