P0019 Technical Description
Crankshaft Position – Camshaft Position Correlation (Bank 2 Sensor B)
If you’re seeing the P0019 trouble code in your car, this guide will help you understand its meaning, symptoms, causes, and how to fix it.
I’ve encountered this issue before and successfully resolved it for many drivers.
We’ll explore what the P0019 code means, the symptoms you might notice, common causes, and step-by-step fixes to get your car running smoothly again.
Let’s get started and solve this problem together.
Key Takeaways
- P2197 means the O2 sensor (Bank 2, Sensor 1) detects a lean air-fuel mixture.
- Symptoms include check engine light, poor fuel economy, rough idling, and engine stalling.
- Common causes are faulty O2 sensor, exhaust leaks, fuel injector issues, and vacuum leaks.
- Fixes involve inspecting and repairing the O2 sensor, exhaust, fuel injectors, and vacuum system.
- Regular maintenance can prevent the P2197 trouble code.
- Addressing the P2197 code promptly ensures optimal engine performance and fuel efficiency.

What Does P0019 Trouble Code Mean?
The P0019 trouble code means there’s a misalignment between the crankshaft and camshaft positions on Bank 2, specifically with Sensor B.
Your engine relies on precise timing between these components to run smoothly. When the alignment is off, your car’s computer detects this discrepancy and triggers the P0019 code.
Bank 2 refers to the side of your engine opposite to Bank 1. In a V6 or V8 engine, this would be the side without cylinder 1.
Sensor B is the second sensor in the system, which typically monitors the camshaft’s position.
This code often pops up due to timing chain or belt issues. These components can stretch, wear out, or even jump a tooth, causing the timing to go out of sync.
Other potential causes include a faulty camshaft or crankshaft position sensor, issues with the variable valve timing (VVT) system, or wiring problems.
When this code appears, your engine might run rough, misfire, or even fail to start. You might also notice a decrease in fuel efficiency or hear unusual noises from the engine.
Ignoring this code can lead to more severe engine damage, so it’s crucial to address it promptly.
In summary, the P0019 code is a sign that your engine’s timing is off between the crankshaft and camshaft on Bank 2.
The most common culprits are timing components, sensors, or the VVT system. Addressing this issue quickly can prevent more extensive and costly engine damage down the road.
P0019 Trouble Code Symptoms
When your car has a P0019 trouble code, you might notice several symptoms. Here are the most common ones:
- Rough idling
- Engine misfires
- Difficulty starting the engine
- Decreased fuel efficiency
- Loss of power
- Check Engine Light (CEL) illuminated
- Unusual noises from the engine
P0019 Trouble Code Causes
Several issues can trigger the P0019 trouble code. Here are the most common causes:
- Stretched or damaged timing chain/belt
- Faulty camshaft position sensor
- Faulty crankshaft position sensor
- Problems with the variable valve timing (VVT) system
- Damaged or worn timing chain guides
- Issues with the timing chain tensioner
- Wiring problems or electrical issues
- Incorrectly installed timing components
How To Fix A P0019 Trouble Code
Fixing a P0019 trouble code involves diagnosing the root cause and performing the necessary repairs. Here’s a step-by-step guide to help you through the process:
1. Scan for Additional Codes
Use an OBD-II scanner to check for any additional trouble codes. Multiple codes can provide more insight into the issue.
2. Inspect Timing Components
Check the timing chain or belt for signs of wear, stretching, or damage. Ensure the timing marks on the crankshaft and camshaft are aligned correctly.
3. Check Camshaft and Crankshaft Position Sensors
Inspect the sensors for any visible damage or wear. Use a multimeter to test the sensors’ resistance and voltage. Replace any faulty sensors.
4. Examine the Variable Valve Timing (VVT) System
Inspect the VVT solenoids and actuators for any signs of damage or wear. Ensure they are operating correctly. Clean or replace faulty components as needed.
5. Inspect Timing Chain Guides and Tensioner
Check the guides and tensioner for wear or damage. Replace any worn or broken parts to ensure proper tension on the timing chain.
6. Check Wiring and Connections
Inspect the wiring and connectors associated with the camshaft and crankshaft position sensors, as well as the VVT system. Look for any signs of corrosion, damage, or loose connections. Repair or replace any faulty wiring or connectors.
7. Reset the Engine Control Module (ECM)
After making repairs, use an OBD-II scanner to clear the trouble codes and reset the ECM. Start the engine and monitor for any recurrence of the P0019 code.
By following these steps, you can diagnose and fix the P0019 trouble code, restoring your engine’s proper timing and performance. If you’re not comfortable performing these repairs yourself, it’s best to consult a professional mechanic.
