Code P0345 Dodge Description

The circuits of the Camshaft Position (CMP) Sensor include a 5-Volt reference circuit supplied by the Powertrain Control Module (PCM), a low reference circuit, and an output signal circuit. The CMP Sensor is a digital output integrated circuit sensing device that is internally magnetically biased. It detects changes in magnetic flux between the high and low points of a tone wheel connected to the camshaft. When each tooth on the tone wheel passes by the CMP Sensor, the sensor electronics use the resulting change in the magnetic field to generate a digital output pulse. The sensor produces a digital ON/OFF DC voltage pulse with a frequency that varies depending on the number of output pulses per revolution of the camshaft, corresponding to the pattern on the camshaft tone wheel. The speed of the camshaft determines the frequency of the CMP Sensor output. The PCM interprets the tooth pattern to determine the position of the camshaft. This information is then utilized to synchronize the engine's ignition timing and fuel injection events. Additionally, the PCM uses the CMP Sensor output data to ascertain the relative position of the camshaft to the Crankshaft, enabling control of the CMP Actuator if it is present.
The Diagnostic Trouble Code (DTC) will be set if, during cranking, at least 2.5 seconds have elapsed with a Crankshaft Position Sensor signal present but no Camshaft Position Sensor signal or with the engine running, the Camshaft Position Sensor signal is lost for at least 0.4 seconds with a Crankshaft Position Sensor signal present.

What are the Possible Causes of the DTC P0345 Dodge?

Low engine oil
Faulty Camshaft Position (CMP) Sensor
Camshaft Position Sensor harness is open or shorted
Camshaft Position Sensor circuit poor electrical connection
Faulty Powertrain Control Module (PCM)

Code Tech Notes

In the event of a failure in either the Crankshaft Position (CKP) Sensor or Camshaft Position (CMP) Sensor, the engine can still start. The Powertrain Control Module (PCM) is capable of determining the engine position and initiating startup based on one of these two inputs. However, there may be a small delay in starting as the PCM needs time to establish synchronization. If either the CKP or CMP Sensor signals are absent during engine cranking, a Diagnostic Trouble Code (DTC) is recorded, and the Malfunction Indicator Lamp (MIL) lights up.

What is the Cost to Diagnose the Code?

Labor: 1.0

To diagnose the P0345 Dodge code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P0345 Dodge Code

What does the OBDII code P0345 mean in a Dodge vehicle?

P0345 indicates an issue with the camshaft position sensor circuit for Bank 2, Sensor 1. It means the signal from this sensor is either missing or out of range.

What are the common symptoms of a P0345 code in a Dodge?

Symptoms may include poor engine performance, rough idling, hard starting, stalling, reduced fuel efficiency, or the Check Engine Light turning on.

What causes the P0345 code to appear in a Dodge?

Common causes include a faulty camshaft position sensor, damaged wiring or connectors, a failed crankshaft position sensor, issues with the timing chain or belt, or a malfunctioning PCM (Powertrain Control Module).

Can I drive my Dodge with a P0345 code?

While it may still be drivable, operating the vehicle with this code can lead to poor performance, potential stalling, and further engine damage. Itâ€™s best to address the issue promptly.

How do I diagnose the P0345 code in a Dodge?

Start by scanning the vehicle with an OBDII scanner, visually inspecting the wiring and connectors for damage, testing the camshaft position sensor with a multimeter, and checking the timing components.

How do I fix the P0345 code in a Dodge?

Repairs may involve replacing the camshaft position sensor, repairing damaged wiring or connectors, inspecting and fixing timing chain issues, or reprogramming or replacing the PCM if necessary.

What is Bank 2, Sensor 1 in relation to P0345?

Bank 2 refers to the side of the engine opposite Bank 1 (usually the side without cylinder 1), and Sensor 1 is the camshaft position sensor on that bank.

How much does it cost to repair a P0345 code in a Dodge?

The cost varies depending on the issue. Replacing a camshaft position sensor typically costs $100â€“$300, while more complex repairs like timing system work or PCM replacement can be significantly higher.

Could a bad crankshaft position sensor cause a P0345 code in a Dodge?

Yes, a faulty crankshaft position sensor can affect the camshaft position sensor's operation, as the two sensors work together to monitor engine timing.

Will clearing the P0345 code solve the problem?

Clearing the code may turn off the Check Engine Light temporarily, but unless the underlying issue is resolved, the code will likely return.
