Short in fuel pressure sensor was repaired, however the check engine light turned back on

Hi,

If the light went off after the repair, it shouldn't have turned back on. Oftentimes, the codes need deleted or erased after repairs, but if it was off when you got it, it sounds like that was done.

Here is what I need you to do. We need to determine if the same code has returned or if there is a new one. Here is a link that explains how it's done. However, if you take it to a parts store, most will do it free of charge.

Let me know what code has set the light to turn on. Also, if you look at your receipt, it should have the original code or codes found. It should start with the letter P followed by 4 numbers.

Take care and I'll watch for your reply.

Hi,

With your neighbor's scanner, clear the code and see if it returns. If it does, then the manufacturer is responsible for repairing it. If you want, I attached the diagnostics below for this vehicle. Take a look through them and let me know if you are comfortable performing them. Also, be careful because a dealership may give you a hard time if something fails. If they know you worked on it, they could decline a repair.

Let me know what you find or if you have questions.

Take care,

Joe

See pics below.

Hi,

If power was removed, there is a drive cycle that goes through to test different circuits. However, it shouldn't turn the check engine light on until something fails; especially since the light was off when you got it and it came back on.

If the vehicle is running properly, entertain their idea. See if it goes off. Hopefully, it will, but since it turned itself back on, I suspect it won't.

Or you could try clearing the code with the scan tool to see if it turns back on. If it does, then suspect the problem still exists.

Let me know what I can do to help.

Take care,

Hi.

I feel that is a good idea. If you have a chance, could you let me know what is found? I'm interested in knowing.

Thanks,

Joe

Hi,

Honestly, a day off has to be spent at the dealership. Ugh! Remember, they have three chances to fix it. One down already. If they can't fix an issue with the fuel pressure sensor, it could cause issues that may put you in danger.

If that is the case, after three attempts, you can claim the Lemon Law and force GM to buy back the vehicle.

Let me know if there is anything I can do to help.

Take care and good luck.

Hi,

I don't know why, but I was thinking about your issue. LOL The check engine did come back after they cleared everything, correct? I'm sorry, I was just wondering.

Take care,

Joe

That's what I thought. They didn't fix the problem. They may believe they did, but something different may be causing it.

I look forward to hearing the results.

Take care,

Joe

Hi,

Hang in there. Even if it is a warranty repair, they get paid by the manufacturer. Did they let you know if they can get to it tomorrow?

Let me know.

Joe

Sound good. Keep me in the loop. I'm interested in knowing what they find and tell you.

Take care of yourself,

Joe
