Seeking assistance for my 2005 Nissan UD truck experiencing limp mode issues. I have diligently followed the manufacturer's guidance to trigger the check engine light's flashing sequence by grounding the engine diagnostic wire and turning the key to the on position. Despite the light flashing 8 times, there seems to be no corresponding code 8 in the UD list, as codes commence at 11. Can anyone provide guidance or insight on this matter?
The error code P0008 indicates that your timing chain needs to be replaced due to wear and tear.
Is the initial flash longer in duration? If so, this would increase the total count to 10, with the following seven flashes bringing it to a total of 17. Are you using a timing chain or is it driven by gears?
The check engine light on my Hino J08E truck is flashing 8 times before pausing and repeating the sequence. There are no additional flashes before or after that could indicate a different code. I attempted to upload a video but was unsuccessful. I am unsure if the issue is related to the timing chain or gear system, but I suspect it may be the chain. Despite the flashing light, the truck runs smoothly until it suddenly goes into limp mode. I can temporarily resolve the issue by turning the key off, restarting the engine, and driving again before it goes back into limp mode. This problem occurs even though the engine has already accumulated 425,000 miles.
According to Spud_Monkey, the code P0008 indicates wear on the timing chain. It seems that the JO8E engine features a gear-driven timing system.
Delmer inquired, "Is the timing mechanism gear driven or chain driven? If it's gear driven, the initial flash being longer could bump up the total count to 17, with the first flash being a 10. Click to learn more about gear-driven timing mechanisms."
Answer: To trigger the check engine light flashing sequence, you can ground the engine diagnostic wire and turn the key to the on position as per the manufacturer's guidance.
Answer: The codes for Nissan UD trucks may start at a number higher than 8, such as 11. It is important to refer to the specific code list for your truck model to correctly interpret the flashing sequence.
Answer: If your truck is stuck in limp mode, it is recommended to diagnose the underlying issue causing this mode and address it promptly. Consulting a professional mechanic or using a diagnostic tool may help in identifying the problem.
