P0345 code definition

The P0345 lawmaking indicates that the car's computer has detected an incorrect voltage reading from the bank 2 camshaft position sensor.

What the P0345 code means

In gild to ensure proper engine timing and right fuel delivery for driving conditions, your auto's estimator needs data about camshaft position and speed. This is delivered past using a stationary electromagnet (camshaft position sensor) in conjunction with teeth on the shaft. Every bit the teeth motility in front of the sensor, the bespeak is blocked, creating a pattern. This blueprint is sent to the car's computer and used to help determine engine timing and fuel delivery. If it is incorrect, and so the automobile's computer will set the P0345 code.

What causes the P0345 code?

A number of potential causes exist for the P0345 code. They include the following:

• Contamination of the sensor by engine oil or transmission fluid
