What Does Engine Code P0017 Mean

P0017 Camshaft Position Sensor A – Circuit Range/Performance

The camshaft position sensor A circuit is responsible for providing the engine control module (ECM) with information about the position of the camshaft. This information is used by the ECM to control the timing of the engine’s valves.

If the ECM detects a problem with the camshaft position sensor A circuit, it will set a P0017 code. This code indicates that the circuit is either out of range or not performing as expected.

There are a number of possible causes for a P0017 code, including

A faulty camshaft position sensor
A damaged wiring harness
A problem with the ECM

So What Does Engine Code P0017 Mean?

P0017 is a generic OBD-II code that indicates that the camshaft timing is retarded. This means that the camshaft is not in sync with the crankshaft, which can cause a variety of problems, including decreased fuel economy, engine misfires, and poor performance.

What Does Engine Code P0017 Mean?

Engine code P0017 is a generic OBD-II code that indicates that the camshaft position sensor A (CMPS) has an invalid signal. This can be caused by a number of problems, including a faulty CMPS, a problem with the wiring to the sensor, or a problem with the engine’s computer.

Symptoms

The symptoms of P0017 can vary depending on the specific cause of the code. Some of the most common symptoms include:

Engine misfire
Rough idle
Reduced power
Check engine light illuminated

Diagnosis

Diagnosing P0017 can be a bit tricky, as there are a number of potential causes. The first step is to connect a diagnostic scanner to the vehicle and retrieve the codes. Once you have the code, you can begin to narrow down the possible causes.

Some of the things you will want to check include:

The CMPS itself
The wiring to the CMPS
The engine’s computer

Repair

Once you have identified the cause of P0017, you can begin to repair the problem. The specific repairs will vary depending on the cause of the code. However, some of the most common repairs include:

Replacing the CMPS
Repairing or replacing the wiring to the CMPS
Reprogramming the engine’s computer

Prevention

There are a few things you can do to help prevent P0017 from occurring, including:

Keeping your engine oil level topped off
Inspecting the wiring to the CMPS regularly
Having your engine’s computer reprogrammed if necessary

Conclusion

P0017 is a relatively common OBD-II code, but it can be a bit tricky to diagnose. However, by following the steps in this article, you can usually track down the cause of the code and get your vehicle back on the road.
