How to replace the MAP Sensor on Chevrolet HHR?

Starting the manifold absolute pressure sensor replacement process requires removing the Throttle Body. The evaporative emission (EVAP) purge tube needs disconnecting from the Intake Manifold before moving forward. Disconnect the wiring harness clips from the Fuel Rail then place the harness out of your working area. Next disconnect the electric connector of the manifold absolute pressure (MAP) sensor and unscrew the MAP Sensor while examining the seal for damage. The MAP Sensor needs replacement when you discover damage to its sealing mechanism. Begin your installation by installing a fresh MAP Sensor seal when needed and afterward place the MAP Sensor and secure its electrical connector. Let the wiring harness rest in place before reattaching its clips on the Fuel Rail then finalize the connection of the evap purge tube to the Intake Manifold. Finally, reinstall the Throttle Body.

The MAP Sensor in Chevrolet HHR cars is a very important same as in any car it shows the positive pressure air that is entering the intake manifold into the engine and communicates this info to the ECU for fuel regulating. In the calculation of air density and the air-fuel mixture for combustion, especially the speed-density method, it is crucial. For the naturally aspirated engines, either the MAP sensor or the mass airflow (MAF) sensor is incorporated but for forced induction engines, both are used. MAP sensor also helps in OBD II, in this case, it is used in the testing of functionality of EGR valve. While boost sensors work in measuring pressures in terms of above atmospheric or gauge pressure, MAP sensors work in measuring absolute pressure and never read negative pressure- the pressures necessary for accurate measurements that include fuel metering, ignition timing and other engine parameters.
