P0019 Saturn 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 Saturn 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 Saturn?
- Mechanical timing fault
- Blocked oil passage
- Low oil level
- Faulty Exhaust ('B') Camshaft Position (CMP) Sensor
- Faulty Crankshaft Position (CKP) Sensor

Frequently Asked Questions about P0019 Saturn Code
1. What does the OBDII code P0019 mean on a Saturn?
P0019 indicates a "Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor 'B'" issue, meaning the engine's computer has detected a misalignment between the crankshaft and camshaft positions.
2. What are the common symptoms of a P0019 code on a Saturn?
Symptoms may include difficulty starting, rough idling, reduced engine performance, decreased fuel efficiency, or an illuminated check engine light.
3. What causes the P0019 code on a Saturn?
Common causes include a faulty camshaft or crankshaft position sensor, a stretched or damaged timing chain, misaligned timing components, oil flow issues, or electrical wiring problems.
4. How do I diagnose the P0019 code on my Saturn?
Start by checking the camshaft and crankshaft position sensors, inspect the timing chain for wear or damage, verify proper oil levels, and look for damaged wiring or connectors.
5. Can low oil cause a P0019 code on a Saturn?
Yes, low or dirty oil can affect the operation of the variable valve timing (VVT) system, potentially leading to a P0019 code.
6. Is it safe to drive with a P0019 code on a Saturn?
Driving with a P0019 code is not recommended as it can lead to engine misfires, poor performance, and potential engine damage if not addressed promptly.
7. How much does it typically cost to fix a P0019 code on a Saturn?
Repair costs vary depending on the cause. Replacing a camshaft or crankshaft sensor may cost $100–$300, while timing chain repairs can exceed $1,000.
8. Can I fix the P0019 code on my Saturn myself?
If you're experienced with car repairs, you may be able to replace sensors or check wiring yourself. However, timing chain or VVT system repairs are best left to professionals.
9. Does resetting the check engine light fix the P0019 code on a Saturn?
Resetting the light may temporarily clear the code, but it won’t resolve the underlying issue, and the code will likely return unless the problem is fixed.
10. How can I prevent a P0019 code from occurring on my Saturn?
Regularly maintain your vehicle by changing the oil on schedule, using the correct oil type, inspecting timing components for wear, and addressing check engine lights promptly.
