How is the camshaft position sensor connected to the PCM?

The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain.

How does the crankshaft position sensor ( CKP ) work?

The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing.

What happens to the crank sensor on a GMC?

The crankshaft sensor on GMC vehicles is synced to the powertrain control module, or PCM. When the crank sensor is replaced, it must be resynced to the PCM. Without resyncing, the PCM cannot properly determine the position of the crankshaft.

What causes a cam sensor to go bad on a crankshaft?

Causes may include: Timing chain stretched, or timing belt skipped a tooth due to wear. Misalignment of timing belt/chain. Tone ring on crankshaft slipped/broken. Tone ring on camshaft slipped/broken. Bad crank sensor. Bad cam sensor. Damaged wiring to crank/cam sensor.

What does the crank sensor tell the PCM?

The signal from the crank sensor also tells the PCM how fast the engine is running (engine rpm) so ignition timing can be advanced or retarded as needed. On some engines, a separate camshaft position sensor is also used to help the PCM determine the correct firing order. The engine will not run without this sensor’s input.

Where are the crankshaft and camshaft sensors located?

Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select Crankshaft sensor (Hall effect) or Camshaft sensor (Hall effect). An engine’s CKP and CMP sensors provide the Engine Control Module (ECM) with critical engine speed, position, and timing reference data.

What does a bad crankshaft sensor reading mean?

Set up the scanner to read engine RPM and crank the engine. The scan tool should read between 100 and 500 RPM. A bad reading indicates that the crankshaft sensor isn’t working right. A reading of zero indicates that the crankshaft sensor has failed completely.

It covers the entire circuit attached to the aforementioned sensor, such as the electric wiring and the powertrain control module (PCM). Thus, replacing the sensor will not always resolve the issue. The camshaft position sensor calculates the speed at which the engine’s camshaft rotates.

What does fault connector on camshaft position actuator mean?

Fault connector of the camshaft position actuator (corroded, loose, or bent, or disconnected pins) Before you attempt to diagnose this error code, make sure that you have some knowledge regarding safety measures as you work with your car. If not, better take it to a professional like me.

What is the p0344 code for a camshaft sensor?

P0344 Code: Camshaft Position Sensor “A” Circuit Intermittent (Bank 1 or Single Sensor) P0345 Code: Camshaft Position Sensor “A” Circuit (Bank 2) P0122 Code: Throttle Position Sensor/Switch A Circuit Low Input

What should clearance be for Camshaft Position Sensor?

Generally, the sensor needs between 0.020” and 0.050” clearance to the reluctor ring or camshaft tooth. If the sensor is cocked to one side or not firmly seated, the clearance will be wrong and the signal will be too weak for the ECU to detect. If the reluctor ring is rubbing on the sensor, the signal will be distorted.

Where is the bank 1 sensor camshaft sensor located?

Where is the bank… Where is the bank 1 sensor b camshaftsensor located on a 2010 traverse 3.6? Mechanic’s Assistant:Which particular sensor are you asking about? And have any trouble codes been triggered? P0017 Mechanic’s Assistant:Are you fixing your Traverse yourself? What have you tried so far? Yes. Just had code tested.

Where is the camshaft position sensor located on a jeep?

The camshaft position sensor (located inside the ignition distributor) gets power from the powertrain control module (PCM) thru’ the WHT/BLK (white with black stripe) wire. This power is in the form of 8 Volts DC. The WHT/BLK wire also feeds the crankshaft position (CKP) sensor and the vehicle speed sensor (VSS) with 8 Volts DC.

What are the symptoms of a camshaft position sensor?

Camshaft Position Sensor Symptoms 1 Extended crank time with a cold engine. 2 Intermittent rough running. 3 Unstable idle. 4 Bucking. 5 Hesitation. 6 (4 more items)

What does a camshaft sensor do in an Audi A4?

On Three Wire Sensor engines, the Camshaft Position (CMP) sensor is a variable reluctance sensor, which is triggered by the high-point mark on one of the camshaft sprockets. The Distributor engine does not use a separate CMP sensor. It utilizes a conventional distributor, equipped with a Hall effect device, for this function.

Where is the camshaft timing pin on a DTC p0340?

It is mounted at the end of the Intake Camshaft (See Fig. 2). When the Camshaft Timing pin comes close to the sensor head, the voltage at the signal wire drops to zero. It rises back to 12 volts when the pin leaves the sensor head. The Camshaft Position Sensor sends this signal to the PCM via the signal wire in the wiring harness (See Fig. 3).

How is the camshaft position sensor connected to the ECU?

The wiring harness should be routed away from the high-tension cable to prevent interference. This procedure will determine if the Camshaft Position Sensor is able to send signal to the ECU. This is done by measuring the voltage across the signal and ground wires of the sensor.

How is the camshaft position sensor connected to the PCM?
