SOURCE: P0340 Code Camshaft Position Sensor


The Camshaft Position (CMP) Sensor detects the position of the camshaft in order to identifiy when piston No. 1 is on its compression stroke. The CMP sensor is used for ignition timing in the Ford DIS igntion system, but not in the EDIS igntion system. Both DIS/EDIS use the CMP signal for synchronizing the firing of sequential fuel injectors.

On the 3.0L vulcan engine, the CMP signal is generated by a single Hall-Effect magnetic switch, activated by a single "vane" spinning around by virture of a synchronized shaft which is driven by the camshaft. 

The CMP sensor & synchronizer/shaft are located behind the intake manifold (i.e., back near the firewall on a Ranger) on the top of the cylinder block. If you just need to replace the sensor, it is a simple job of unplugging the electrical connector and removing the screws holding the sensor in place. Here is a sketch of the sensor to give you an idea what to look for:

change the crankshaft positon sensor in the rear of the engine above the oilfilter. Also check the wiring to this sensor, they have a problem shorting out. You have to change the camshaft and crankshaft sensors at the same time. Make sure you give your car a major tune up. Did you check yor starter?.........runjoe

P0340 FORD - Camshaft Position Sensor Circuit Bank 1 Sensor 1Possible causes- Faulty Camshaft Position Sensor
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty starter motor
- Starting system circuit
- Dead (Weak) battery
P0340 FORD Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module(ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The camshaft position sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor.

When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change.

When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

Can u tell me what the problem of this code PO340


I have a 1999 BMW 740 il My SES light came on so I hooked up my OBD code reader p0340 - Camshaft Position Sensor Circuit Malfunction is what came up. so I went to the BMW parts department and bought the Camshaft Position Sensor.
I Replaced the with the new. My SES light was still on so I hooked up the OBD reader again hoping it may reset my SES light but it didn't what did happen is the OBD reader came up with the same code (p0340 - Camshaft Position Sensor Circuit Malfunction) witch is what I just replaced. now I'm at a loss. I'm not sure how to reset my SES light and if I just replaced the Camshaft Position Sensor why dose it the OBD code p0340 still come up. Any suggestions?

In a Toyota Tundra v8 4.7l, after I change the Timing Belt, why does Check Engine comes on, and it shows Troubleshooting P0340.


Symptoms Symptoms can include:
  • Hard starting or no start
  • Rough running / misfiring
  • Loss of engine power
Causes A code P0340 could mean one or more of the following has happened:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed
Possible Solutions With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

P0340 code


This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM.

A code P0340 could mean one or more of the following has happened:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • a crankshaft position sensor may have failed
With a P0340 Code diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required
The location of these 2 sensors vary. Usually they can be found on the back of the engine or on the transmission. I hope this gives you some direction. Thanks for using FixYa!

Sincerely,

JC
