General Installation Practices

NOTE: Disconnect Battery

Before unplugging your MAP sensor, it is important to disconnect both batteries and let the ECM discharge for at least 15min.

If you rush this step and unplug the MAP sensor, it can flag a Check Engine Light in the ECM on startup.


MAP Sensor Relocation Kit Installation

Locate MAP Sensor

1. Locate MAP sensor.

It is found on top of your intake manifold.

Slide locking Tab

Use MAF cleaner only

Important: Use Mass Air Flow Cleaner Only.

Solvents such as brake cleaner will damage the sensor.

While GM does not recommend cleaning, we have seen favorable results using Mass Air Flow (MAF) Sensor Cleaner, available at most auto parts stores.

Try not to overly spray the sensing wire; a rag or brush can be used for stuck-on debris.
