Circuit Description
WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
The intake camshaft position (CMP) sensor produces a 1X signal for each revolution of the intake camshaft. This signal is used for startability. If the PCM does not receive a crankshaft position (CKP) sensor signal, the engine should still start based off of the information from the CAM. The CMP is connected directly to the powertrain control module (PCM) and consists of the following circuits:
- A 12-volt reference circuit
- A low reference circuit
- A CMP sensor signal circuit
If the PCM does not receive a CAM sensor pulse, DTC P0340 will set.
