What code is po340?

What code is po340?

What Does P0340 Mean? The camshaft position sensor located in the internal combustion engine monitors the position and rotational speed of the camshaft. When the trouble code P0340 is set, the ignition spark and fuel injector timing fails due to the engine not knowing when to fire these components.

What are the possible causes of the p0340 code?

P0340 Possible 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.

What does the p0340 camshaft position sensor do?

P0340 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.

How much does it cost to repair a car p0340?

The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. When is the P0340 code detected? The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning.

Why is my DTC p0340 CMP sensor not working?

Depending on year, make, and model, DTC P0340 or P0345 may have number of causes. Here are some of the most common. Faulty Sensor – If the sensor coil is open or shorted, then it will generate no signal. Poor Installation – A good CMP signal is highly dependent on placement.

What to do if your camshaft position sensor says p0340?

Visually inspect the camshaft position sensor connector in search of corroded or broken connectors. Make any other repairs (if other codes are present) to make sure that other codes are not sources of the trouble code P0340. Check your camshaft position sensor’s voltage, ground, and signal readings with a multimeter.

What does the p0340 OBD-2 trouble code mean?

What the P0340 code means. The camshaft position sensor calculates the rotational speed of the camshaft and where the camshaft is positioned in that rotation. The camshaft sensor sends a signal to the Power Control Module (PCM) to communicate this information.

What’s the difference between p0335 and p0340?

A similar code is P0335, Crankshaft Position Sensor “A” Circuit Malfunction. Like P0340, P0335 also warns about a problem in a sensor’s electric circuit. The difference is that P0335 covers the crankshaft that converts engine power into forward motion, while P0340 involves the camshaft that controls the intake and exhaust valves.

What causes a p0340 to set on a Mustang GT?

Ford Trucks / Mustang GT – An alternator phase problem, such as a blown diode or open coil, may cause so much electrical interference that the CMP signal gets distorted, causing a P0340 / P0345 DTC to set, among others, in spite of there being no actual problem with the CMP sensor or wiring.
