Crankshaft Position (CKP) Sensor
CKP sensor is a Hall Effect magnetic switch. The Hall Effect switch is activated by vanes on the crankshaft damper and pulley assembly. The Profile Ignition Pick-up (PIP) is a crankshaft position signal that is sent to the PCM. The PIP signal generated by the Hall Effect sensor provides base timing and RPM information to the PCM.
Data Link Connector (DLC) & Self-Test Input (STI) Connector - The 6-pin Data Link Connector (DLC) is used to perform the Quick Test diagnostic procedure. The STI is a single-pin connector located next to the DLC. When the STI wire is connected to SIG RTN terminal of DLC, fault code output function is activated.
