Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The engine speed is monitored by the powertrain control module (PCM) through the crankshaft position (CKP) sensor. The CKP is hardwired directly to the PCM. The status of the CKP is sent from the PCM to the instrument cluster over the communication network.
