Quick Answer
P0008 means: P0008 indicates a problem with the engine position timing system, often related to the crankshaft and camshaft synchronization.
Can I drive with P0008? It's advisable to address this code immediately to prevent engine damage.
Common Questions
What does P0008 mean and how does it affect my car?
The P0008 code indicates that your engine's camshaft and crankshaft positions are not synchronized as they should be. This can lead to poor performance, rough idling, and even stalling. If ignored, it can cause serious engine damage over time.
What are the most common causes of P0008 and how much does it cost to fix?
Common causes include a stretched timing chain, faulty sensors, or oil sludge. Repair costs for timing chain replacement can range from $600 to $1200, while sensor replacements may cost between $150 and $400.
Can I drive my car with P0008 or should I stop immediately?
It's not recommended to drive with the P0008 code active. Continuing to drive can lead to more severe engine damage, so addressing this issue promptly is crucial.
How can I diagnose P0008 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for DTCs, view live data from engine sensors, and analyze freeze frame data to understand the conditions under which the P0008 code was triggered.
What vehicles are most commonly affected by P0008?
This code is frequently seen in models such as the 2011-2018 Chevrolet Malibu, 2013-2015 Cadillac ATS, and various Ford models from the same years. Always check for any recalls or TSBs that might apply.
How can I prevent P0008 from happening again?
Regular maintenance, including timely oil changes and ensuring proper coolant levels, can help prevent issues with the timing system. Additionally, addressing any engine performance issues immediately can minimize wear on components.
What is P0008?
The diagnostic trouble code (DTC) P0008 indicates a problem with the engine position system performance. Specifically, it suggests that the crankshaft and camshaft timing is not aligned correctly, leading to potential issues with engine performance. This code is prevalent in various vehicles, notably the 2011-2018 Chevrolet Malibu, but can also appear in other makes and models. When the engine control module (ECM) detects that the actual position of the camshaft is out of the expected range, it triggers the check engine light, alerting the driver of an underlying issue. If left unresolved, this can lead to poor engine performance, increased emissions, and potential engine damage. Drivers may notice a decline in fuel efficiency, or the vehicle may experience rough idling, stalling, or difficulty starting. Addressing this DTC promptly is crucial to maintaining vehicle performance and preventing further complications.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P0008 is present:
- Check engine light stays on constantly, indicating a persistent issue that needs attention.
- Engine hesitates during acceleration, making it difficult to maintain speed or respond to throttle input.
- Fuel economy decreased by 10-15%, leading to increased overall running costs.
- Rough idling, where the engine may shake or vibrate more than usual when stopped.
- Difficulty starting the engine, which may involve extended cranking times before the engine fires up.
Possible Causes
Most common causes of P0008 (ordered by frequency):
- The most common cause is a stretched timing chain or belt, with a likelihood of about 60%. This can happen over time due to wear and tear.
- Another common cause is a faulty camshaft or crankshaft sensor, which can misread the positions and cause timing issues.
- Oil sludge buildup can prevent proper lubrication of the timing chain, leading to premature wear. Regular oil changes can help prevent this.
- Less common but serious causes include a malfunctioning ECM, which may not correctly interpret the timing signals, leading to performance issues.
- Rarely, a broken timing chain can occur, which may result in immediate engine failure if not addressed quickly.

Money-Saving Tips for P0008
- Start with the most common and least expensive repairs first
- Use GeekOBD APP to confirm diagnosis before replacing expensive parts
- Consider preventive maintenance to avoid future occurrences
- Compare prices for OEM vs aftermarket parts based on your needs
- Address the issue promptly to prevent more expensive secondary damage
Diagnostic Steps
Professional P0008 Diagnosis Process
Follow these systematic steps to accurately diagnose P0008. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test suspected components, focusing on the sensors (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes using the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
