Description of DTC code P0017

The CKP sensor (Crankshaft Position Sensor) and the CMP sensor (Camshaft Position Sensor) work together in order to control the delivery and the time. The two sensors have a reluctor ring, which passes through a magnetic sensor. In addition, the ring generates a voltage that indicates the position of each component that indicates the sensor respectively.

The Crankshaft Position Sensor (CKP) is part of the primary ignition system and is the trigger. It takes into account the position of the crankshaft relays, and then sends that information to the Power Train Control Module (PCM) to manage the timing of the spark.

On the other hand, the Camshaft Position Sensor (CMP) detects the position of the camshaft, and then transmits that information to the Powertrain Control Module (PCM). Then the PCM with these data can determine the beginning of the sequence of the injector.

These sensors and their two axes are linked by a belt or distribution chain. The timing of the cam like the crank should be precise. In case the PCM detects that both signals (cam and crankshaft) are out of time for a specific number of turns, the DTC code P0017 OBD2 is established.

Symptoms of fault code P0017

  • Check Engine light illumination.
  • Engine performance is reduced.
  • The engine may not start.

Causes of OBD2 P0017

Fault code P0017 OBD II is established due to the following:

  • Wear of the belt or distribution chain.
  • The timing belt or chain may be misaligned.
  • Perhaps the tone ring on the crankshaft is defective.
  • Tone ring on the camshaft may be defective.
  • Cables leading to the defective Camshaft Position Sensor.
  • CMP sensor controller solenoid shorted.
  • Defective CKP sensor.
  • CMP sensor defective.

Possible solutions of the DTC code P0017

When establishing the DTC code P0017 you must do the following to correct it:

  • Performs an inspection of the cam and the CKP Sensor. Also check your cables and connectors. If you find worn or defective cables you should proceed to perform the necessary repairs or replace if necessary.
  • With an endoscope you should check the cam and crankshaft patterns. If you notice that a pattern is missing, it is indicative that one of the sensors is defective, or a ring tone is sliding. For that, you must remove the cam gear together with the crankshaft balancer. Then, check the tone rings for correct alignment and good connection. If there are no problems in these, change the sensor.
  • If after making the readings, the signal obtained is within the expected range, you should check that the distribution chain or belt has a correct alignment. If you notice that it is misaligned, check the tensioner, as it may be defective allowing the chain to slide. It also checks the status of the chain, as it may be stretched, repaired or changed as necessary.
