The crankshaft and camshaft are vital parts of your engine. They ensure the efficient performance of your engine. The camshaft and crankshaft position sensors are used to monitor the positions of the camshaft and crankshaft respectively. The powertrain control module (PCM) of the vehicle uses the data of these sensors to control the different functions of the engine. When the PCM monitors an issue with the Bank 2 crankshaft and camshaft positions, it triggers the diagnostic trouble code (DTC) P0019. This article describes the P0019 engine code meaning, causes, symptoms, and how to fix it.
P0019 Code Definition
The P0019 code stands for “Crankshaft Position – Camshaft Position Correlation (Bank 2 Sensor B).”
Bank 2 indicates the engine side opposite bank 1. Sensor B indicates the exhaust camshaft.
What does the P0019 Code Mean?
The P0019 code is triggered when the powertrain control module (PCM) of your vehicle observes that the bank 2 crankshaft and exhaust camshaft are out of sync.
A timing chain or belt connects the camshafts and crankshafts in an engine. The crankshaft position sensor (CKP) detects the position of the crankshaft and sends this information to the powertrain control module (PCM).
Similarly, a camshaft position sensor (CMP) tracks the position of each camshaft and relays that information to the PCM. Proper timing between the cam and crankshaft is crucial for efficient engine performance and to avoid potential engine problems.
If the Engine Control Module (ECM) detects that the bank 2 intake camshaft and crankshaft are not in the correct position, it will trigger code P0019.
Causes of P0019 Code
- Wiring issues: Damaged or corroded wiring can cause incorrect signals to be sent to the ECM, leading to the P0019 code.
- Faulty camshaft position sensor: The camshaft position sensor may be faulty, causing incorrect readings to be sent to the engine control module (ECM).
- Faulty VVT solenoid: The VVT solenoid controls the oil flow to the camshaft phaser, which adjusts the timing of the camshaft. If the solenoid is malfunctioning, it may not allow oil to flow properly, causing the camshaft timing to be off.
- Failed camshaft phaser: The camshaft phaser adjusts the timing of the camshaft. If it fails, it can cause the camshaft to be out of sync with the crankshaft, which can trigger the P0019 engine code.
- Low or dirty engine oil: If the engine oil is low or contaminated, it can cause problems with the VVT system, which can trigger the P0019 code.
Symptoms of P0019 Code
- Starting problems: The engine may have trouble starting, or it may not start at all.
- Illuminating check engine light: The flashing check engine light is one of the clear symptoms of the P0019 code.
- Engine knocking: A malfunctioning VVT system can cause the engine to make a knocking sound.
- Engine performance issues: You may experience a lack of power or acceleration, rough idling, or stalling.
- Engine misfires: Misfires can occur if the camshaft timing is off.
- Poor fuel economy: A malfunctioning VVT system can cause the engine to use more fuel than necessary.
How to diagnose P0019 Code
- Check for other codes: If there are other codes present, they may provide additional information about the P0019 code.
- Check the oil level and quality: Low or dirty oil can cause issues with the VVT system. Make sure the oil level is correct and the oil is clean and of the proper viscosity.
- Inspect the camshaft position sensor: Check for signs of damage or wear on the camshaft position sensor. If the sensor is damaged or faulty, it will need to be replaced.
- Check the camshaft phaser: The camshaft phaser controls the timing of the camshaft. If it’s malfunctioning, it may need to be replaced.
- Check the wiring and connectors: Inspect the wiring and connectors for any signs of damage or corrosion. Repair or replace any damaged wiring or connectors.
- Inspect the VVT solenoid: Check the VVT solenoid for proper operation. If it’s not functioning correctly, it may need to be replaced.
- Use a scan tool: Use a scan tool to monitor the camshaft position sensor and VVT solenoid signals. This will help determine if they’re functioning correctly.
- Perform a road test: Take the vehicle for a road test to determine if the symptoms are still present after repairs have been made.
Common P0019 Code Diagnostic Mistakes
- Not checking the oil level and quality: Low or dirty oil can cause issues with the VVT system, which can trigger the P0019 code. It’s important to check the oil level and quality before replacing any components.
- Failing to check the camshaft phaser: The camshaft phaser adjusts the timing of the camshaft. If it’s malfunctioning, it can cause the camshaft to be out of sync with the crankshaft, triggering the P0019 code. It’s important to check the camshaft phaser before replacing any components.
- Replacing the camshaft position sensor without checking the wiring: Faulty wiring can cause the camshaft position sensor to send incorrect signals to the engine control module (ECM). It’s important to check the wiring before replacing the sensor.
- Overlooking the VVT solenoid: The VVT solenoid controls the oil flow to the camshaft phaser, which adjusts the timing of the camshaft. If the solenoid is malfunctioning, it can cause the camshaft timing to be off, triggering the P0019 code. It’s important to check the VVT solenoid before replacing any components.
