P0019 exhaust camshaft towards advance - 2008 Mercedes-Benz ML 350

P0017 timing chain Chevy Colorado P0017 Case Study Part 1
155,000 miles This is not a DTC for the crank sensor . This is for variable valve timing .
DTC P0017: Crankshaft Position (CKP) - Exhaust Camshaft Position (CMP) Correlation Bank 1
The camshaft position (CMP) actuator system enables the engine control module (ECM) to change the timing of the camshafts while the engine is operating. The CMP actuator solenoid signal from the ECM is pulse width modulated (PWM). The ECM controls the CMP actuator solenoid duty cycle by controlling the amount of solenoid ON time. The CMP actuator solenoid controls the advance or the retard of each camshaft. The CMP actuator solenoid controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the CMP actuator solenoid. The ECM controls the solenoid by grounding the control circuit with a solid state device called a driver. The ECM compares the camshaft position or the camshaft angle, to the position of the crankshaft.

Your a little out of your league on this ! Your best bet ,take it to a qualified repair shop !

• Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, camshaft sensor, crankshaft sensor, or timing chain can cause this DTC to set.
• An actuator that is in the full advance or retard position can cause this DTC to set.
• The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft. Or, the crankshaft reluctor wheel has moved and is no longer referenced to top dead center (TDC).
• Observing the desired and actual camshaft angle parameters, with a scan tool before a DTC sets, may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

One crank sensor. It needs to go on a scanner. Both sensors are probably OK. Your problem is most likely the timing chains or guides. If ti were the crank sensor, it wouldn't start. Cam sensor would throw a cam code. Correlation means the crank and cam are not in sync. If you have VVT, it could be the actuator.

Before you replace a part you may or may not need . Why ? What code ? Does the vehicle run ? There has been a lot of confusion on these vehicles with variable valve timing , mixing up cam sensors with camshaft actuators

The presence of DTCs P0008 and P0009 along with P0016, P0017, P0018, and P0019 indicates a possible condition with the primary timing chain and the alignment between both intermediate sprockets and the crankshaft.

- Stretched timing chain
- Failed camshaft actuator or actuator solenoid

The Engine Control Module (ECM) monitors the position of both camshafts and the crankshaft. The ECM performs a test for misalignment between both camshafts on one bank of the engine and the crankshaft. During the test the ECM learns the position of the camshafts and the crankshaft. While the engine is idling, the ECM compares the position of both the camshafts and the crankshaft with the learned value. The ECM will set the P0008 code if both learned values for one bank of the engine are exceeding a calibrated threshold in the same direction.

DTC P0014 Exhaust Camshaft Position (CMP) System Performance.

The cam phasing system is a hydraulically actuated phase shifting mechanism. The powertrain control module (PCM) supplies the ignition positive driver and ground circuits. A pulse width modulated (PWM) driver controls the amount that the camshaft actuator solenoid assembly advances or retards the exhaust camshaft. The exhaust camshaft is commanded to a maximum ****** position of 25 degrees. When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. The maximum advance rate has a 0 percent duty cycle. Other than when the camshaft is at full advance, a 50 percent duty cycle is used to maintain a steady ****** angle.

Remove Cam Phaser Solenoid and inspect it to ensure that all 3 screens are intact. Chances are you will need to replace this Solenoid and change the oil immediately.

Hello..

Take it to Autozone or Advanced auto and get an engine diagnostic and ask them to printout the results. Most times it's a sensor.
