Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The circuit uses 2 different types of crankshaft position (CKP) sensors. The CKP sensor B is connected directly to the ignition control (IC) module, and consists of the following circuits:
- The CKP sensor 1 signal circuit
- The low reference circuit
The CKP sensor A connects directly to the powertrain control (PCM) module, and consists of the following circuits:
- The 12-volt reference circuit
- The medium resolution engine speed signal circuit
- The low reference circuit
If the PCM detects an incorrect number of CKP pulses, DTC P0336 sets.
