How to check if camshaft position sensor is working?

Check if the Camshaft-Position-Sensor connector is fully inserted into the sensor. Check the wiring harness for possible damage (broken or shorted wires). 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.

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).

What happens when the camshaft timing pin leaves the sensor head?

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).

What is the Diagnostic Manual for a Chevy diesel?

OPERATION, DIAGNOSIS AND REPAIR MANUAL FOREWORD This supplemental manual is designed to provide dealer service personnel with information on diagnosing, maintaining and servicing the diesel fuel injection systems used in Chevrolet passenger cars and light-duty trucks equipped with diesel engines.

Where is the fuel pressure gage on a Duramax?

You will notice a hydraulic style fitting at the front right side of the engine, this is for a fuel pressure gage to test the suction side, good luck finding a fitting to snap on to it,I had to get a Kent Moore gage for 400 bucks,I use it all the time as well as a Tech 2 scan tool. I consider these a must for serious Duramax work.

What kind of fuel does a Chevrolet diesel engine use?

What is the code on the Duramax fuel injector?

Low and behold, the P1249 had returned as it had numerous times before. But the only code displayed was a P0205, which indicated a circuit fault on #5 fuel injector. Working quickly before the cylinder heads warmed up, we removed the FICM connectors and repeated the pin test.

Where is the fuel pressure sensor on a GMC diesel?

The engine control module (ECM) controls the fuel pump pressures by using two fuel pressure regulators, fuel pressure regulator 1 is located on top of the fuel injection pump and fuel pressure regulator 2  (7) is located on a fuel rail  (2). The fuel pressure sensor  (4) provides a voltage signal to the ECM to indicated fuel rail pressures.
