Circuit Description
WARNING: This page is about a different car, the 2006 GMC Yukon XL, 2006 Chevrolet Suburban, and 2006 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
The crankshaft position (CKP) sensor signal indicates the crankshaft speed and position. The CKP sensor is connected directly to the powertrain control module (PCM), and consists of the following circuits:
- The 12-volt reference circuit
- The low reference circuit
- The CKP sensor signal circuit
If the PCM detects no signal from the CKP sensor for more than 3 seconds, DTC P0335 sets.
