P0019 Code - Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor 'B'
Quick Answer
The Crankshaft Position (CKP) sensor is a permanent magnet generator, known as a variable reluctance sensor. Common causes include Mechanical timing fault, Blocked oil passage, Low oil level. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0019 Description
The Camshaft Position (CMP) sensor is triggered by a notched reluctor wheel built into the exhaust camshaft sprocket. The CMP sensor provides 6 signal pulses every camshaft revolution. Each notch, or feature of the reluctor wheel is of a different size for individual cylinder identification. This means the CMP and crankshaft position (CKP) signals are pulse width encoded to enable the PCM to constantly monitor their relationship. This relationship is used to determine camshaft actuator position and control its phasing at the correct value. The PCM also uses this signal to identify the compression stroke of each cylinder, and for sequential fuel injection. The CMP sensor is connected to the PCM by a 12-volt, low reference, and signal circuit.
What are the Possible Causes of the DTC P0019?
- Mechanical timing fault
- Blocked oil passage
- Low oil level
- Faulty Exhaust ('B') Camshaft Position (CMP) Sensor
- Faulty Crankshaft Position (CKP) Sensor
How to Fix the DTC P0019?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0019 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 P0019 Code
1. What does OBDII code P0019 mean?
P0019 indicates a problem with the correlation between the crankshaft position and camshaft position for Bank 2 Sensor 'B,' which can affect engine timing.
2. What are the common symptoms of code P0019?
Symptoms may include engine misfires, rough idling, reduced fuel efficiency, lack of power, and difficulty starting the engine.
3. What causes code P0019?
Common causes include a faulty camshaft or crankshaft position sensor, timing chain or belt issues, stretched timing components, or oil flow problems to the camshaft actuators.
4. How do I diagnose code P0019?
Diagnosis typically involves inspecting the timing chain or belt, testing the crankshaft and camshaft sensors, checking engine oil levels, and evaluating the camshaft actuator's functionality.
5. Can low oil levels cause code P0019?
Yes, insufficient oil levels or dirty oil can impair the camshaft actuator operation, leading to timing correlation issues and triggering code P0019.
6. Is code P0019 serious?
Yes, P0019 can lead to severe engine performance issues and potential damage if not addressed promptly.
7. How do you fix code P0019?
Repairs may include replacing faulty sensors, adjusting or replacing timing components, cleaning or replacing the camshaft actuator, or ensuring proper oil levels and quality.
8. Can a faulty camshaft position sensor cause code P0019?
Yes, a malfunctioning camshaft position sensor can disrupt timing signals, causing the P0019 code.
9. Does code P0019 affect only certain engines?
Code P0019 typically occurs in engines with variable valve timing (VVT) systems and dual overhead camshafts.
10. Can I drive with code P0019?
Driving with P0019 is not recommended, as it can lead to engine damage or unsafe driving conditions.

I had P0019 code on my 2008 E350. I changed the cam shaft pos. sensors. The code keeps coming back. Any suggestion???
-
The problem is either the "Camshaft" Position Sensor or the "Crankshaft" Position Sensor. I you have already replaced the the "Camshaft" Position Sensor, then you have to replace the "Crankshaft" Position Sensor
