What is the function of a camshaft position sensor?
What is the function of a camshaft position sensor?
This sensor negates the need for manual distributor timing. The camshaft position sensor is used to determine which cylinder is firing to synchronize the fuel injector and coil firing sequence.
How does the camshaft position sensor work on a Dodge?
The sensor returns a digital ON/OFF DC voltage pulse of varying frequency output pulses per Camshaft revolution that represents an image of the camshaft tone wheel. The frequency of the CMP Sensor output depends on the velocity of the camshaft. The PCM decodes the tooth pattern to identify the camshaft position.
What are the symptoms of a camshaft sensor problem?
You may have noticed the tell-tale signs of a failing camshaft position sensor while driving your 2004 Intrepid. The symptoms include a hesitation or stumble when accelerating from a light, and a P0340 diagnostic trouble code stored in the memory of the on-board computer.
How does a CMP sensor work on a camshaft?
The sensor detects magnetic flux changes between the peaks and valleys of a tone wheel attached to the camshaft. As each tooth rotates past the CMP Sensor, the resulting change in the magnetic field is used by the sensor electronics to produce a digital output pulse.
How much does a camshaft sensor circuit cost?
Most auto repair shops charge between $75 and $150 per hour. The Camshaft Position (CMP) Sensor circuits consist of a Powertrain Control Module ( PCM) supplied 5-volt reference circuit, a low reference circuit, and an output signal circuit.
The sensor returns a digital ON/OFF DC voltage pulse of varying frequency output pulses per Camshaft revolution that represents an image of the camshaft tone wheel. The frequency of the CMP Sensor output depends on the velocity of the camshaft. The PCM decodes the tooth pattern to identify the camshaft position.
What does it mean when your camshaft sensor says p0340?
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.
What are the codes for the crankshaft position sensor?
First code was Camshaft position sensor – Replaced sensor Problem returned 1 week later Second code was Crankshaft sensor – Replaced sensor Problem returned 2 weeks later Third visit to mechanic computer now has (P0016, P0335b, P0339) 2 of these codes have come back and with sensors replaced feel it…
How to diagnose p0340 OBD-II trouble code?
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
