Subject:
Information on Stage Kit TMAP Sensor Modification

Models:
2008-2009 HHR SS

Equipped with 2.0L Engine (VIN X - RPO LNF)

When installing the GM Performance Parts accessory upgrade Stage I Turbo kit # 19212670 on a 2008-09 HHR SS, the intake air pressure temperature (TMAP) sensor interferes with the charge air cooler (CAC) pipe. The TMAP sensor is located on the charge air duct between the intercooler and the engine. The sensor requires modification before assembly or leaks may occur. Following these steps will prevent any concerns when mounting the TMAP to the duct pipe.

Inspect/Removal of Tap





Inspect the TMAP sensor when mounted on the charge air duct. Note how the TMAP sensor is not mounted flush on the duct (1).





Carefully remove the boss (1) until the TMAP will mount flush on the duct. The boss interferes with the anti-rotation bar on the duct.
