Circuit Description
WARNING: This page is about a different car, the 2004 GMC Safari and 2004 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.
The powertrain control module (PCM) uses the crankshaft position (CKP) sensor to detect crankshaft speed and position. The CKP sensor connects to the PCM through the following circuits:
- The 12-volt reference circuit
- The low reference circuit
- The CKP sensor 1 signal circuit
If the PCM detects no signal from the CKP sensor for more than 3 seconds, DTC P0335 sets.
