P0008 Code – Engine position system -engine performance Bank 1

The P0008 code is a generic powertrain code, indicating that the Engine Control Module (ECM) has detected a problem with the engine’s timing. This code is typically triggered when there is a difference in the timing between the camshaft and the crankshaft. This can lead to a variety of issues, including reduced power, poor fuel efficiency, and even engine damage.

If you’re experiencing issues with your vehicle and the check engine light is on, it’s important to have the code diagnosed and repaired as soon as possible. Continuing to drive with a P0008 code can potentially cause further damage to your engine, leading to more costly repairs down the line.

The timing of the crankshaft and camshafts in an engine must be precise. This is achieved through the use of timing sprockets and a timing belt or chain. What is the “timing” as it is? The crankshaft and camshaft(s) are connected by either a belt or chain. For example, as cylinder 1 is pushed up to top-dead-center on the compression stroke by the crankshaft, the valves for cylinder 1 should be closing and the spark plug should be firing. If the timing is off by even a few degrees, it could result in poor performance and fuel economy or even catastrophic engine failure.

Causes of OBD-II Code P0008

There as some more excessive list of the reasons, but we’ve shortened it to 3 main which accounted as a majority among of the all cases.

faulty timing chain or belt. It is the most common cause of a P0008 code. Depends on what is installed on your engine – chain or belt, thіs component is responsible for keeping the camshaft and crankshaft in sync, and when they fail, the timing of the engine can become disrupted. If the timing is off by even a small amount, it can cause the engine to run poorly and can potentially cause damage.

oil pressure is low. Possible cause of a P0008 code is a problem with the engine’s oil pressure. The camshaft and crankshaft are lubricated by oil, and if there is not enough pressure or flow, the timing can become disrupted. This can be caused by a faulty oil pump, a clogged oil filter, or low oil levels.

sensor lies or does not work at all. Other potential causes of a P0008 code include a faulty camshaft or crankshaft position sensor, a malfunctioning ECM, or wiring issues. These can all cause problems with the timing of the engine, leading to reduced performance and potential damage.


The OBD2 code P0008 can indicate a serious issue with the engine’s camshaft or crankshaft timing, which can lead to engine damage if left unaddressed. As a result of any reason calling this code, the engine more or less is going to be imbalanced. You don’t have to post the fix back for whatever reason. 

The complexity of diagnosing a P0008 code means that it is generally not a DIY repair and is best left to experienced mechanics. Regular maintenance and inspections can also help prevent this code from appearing in the first place.

Common Questions

To diagnose the P0008 code, a mechanic will typically start by using a diagnostic scanner to retrieve any stored codes and freeze frame data. They will then inspect the engine’s timing system for any signs of wear or damage, such as worn timing chains or sprockets. If no issues are found with the timing system, the mechanic may proceed to test the engine’s oil pressure to ensure it meets the manufacturer’s specifications.

Further diagnostic steps may include testing the engine’s camshaft position sensor, crankshaft position sensor, and the wiring and connectors associated with these sensors. The fuel system may also be inspected to ensure proper pressure and flow.

Driving is not recommended. It means you can continue driving home or straightaway to the service station.

The severity of the P0008 code depends on the symptoms and how quickly the issue is addressed. If the check engine light is illuminated, but there are no other symptoms, it may be safe to drive the vehicle to a mechanic for diagnosis and repair. However, if the engine is running poorly or there is a noticeable decrease in performance, it is recommended to avoid driving the vehicle until the issue is resolved. Ignoring the code could cause damage to the engine and result in costly repairs.
