The CMPS Electronic Circuit consists of the Camshaft Position Sensor, wiring harness, and the ECU.
The problem could be a defective CMPS. Envoy, Rainer, Trailblazer The PCM also uses this signal to identify the compression stroke of each cylinder, and The Camshaft Position (CMP) sensor is a 3-wire sensor that provides a digital output signal.
Disconnect the CMP sensor jumper harness (2) and the engine harness (3) electrical connectors . The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position .
L, L, L Engine PCM C1 Connector Pinout (1 of 2). Click image to see .
2, LT GRN, , Crankshaft Position Sensor B+ Supply. 3, PNK/BLK. uses the CMP (camshaft position sensor) to figure out what it should set the timing at.
The first thing you need to check is all of the wiring you can see. Camshaft position sensors go bad a lot more than PCM’s do so I would suspect that first.Have a gmc envoy , has a code po cam position sensor schematron.org has already had a new sensor and – Answered by a verified GM Mechanic The only two options left is a wiring issue or the Powertrain Control Module is bad.
Has the wires been check for opens and shorts between the Cam sensor and the Powertrain Control Module. Trailblazer Pcm Location. welcome to my blog here I will show you a little more what you are looking for Trailblazer Pcm Location below there are some photos and a little about Trailblazer Pcm Location that you can see and read, hopefully in accordance with what you are looking for.
The Camshaft Position (CMP) sensor is a 3-wire sensor that provides a digital output signal. The wire circuits consist of an engine control module (ECM) supplied 5-volt reference circuit, a low reference circuit between the CMP sensor and the ECM, and an output signal circuit from the CMP sensor to the ECM.
When you have problems with the Trailblazer camshaft position sensor you often find different codes set in the on board computer memory. In fact the two most common codes associated with the camshaft position sensor failure remain the P But you can set codes from P all the way through P Jun 12, · camshaft sensor pigtail wiring diagram I have a Chevrolet Trailblazer LS I6 L. I was recently looking at the sensor connected to the fan and bumped the CPS and the wires on the pigtail came loose from where the previous owner had used electrical tape to reconnect them.Check Engine Code P – Causes and FixesResolve the Trailblazer Camshaft Position Sensor Problem
