DR - Testing Notes

DESCRIPTION
The Powertrain Control Module (PCM) uses the Cylinder Identification (CID) signal information for fuel injector synchronization. The CID signal is generated by a dual hall-type Crankshaft Position (CKP) sensor with a 50% duty cycle and an amplitude that varies from 0.4 volts to B(+).

NOTE
You should enter this Pinpoint Test only when you have been directed here from Diagnostic Routines.

REMEMBER
This Pinpoint Test is intended to diagnose only the following:

- Harness circuits: CID(+), CID(-), CID, SIG RTN, VPWR

- Crankshaft position sensor

- PCM
