Shut off while driving, codes P0171, P0117 and P0138

Hi,

Okay, the p0138 is related to an oxygen sensor, but i feel it is set as a result of the p0117, which is related to the coolant temperature sensor. The p0117 could also be tied into the p0171. That indicates a lean fuel mixture.

The coolant temperature sensor is responsible for telling the computer how cold or warm the engine is. If it is indicating it is at operating temp or has failed, it can cause the computer to create a lean fuel mixture, thus setting the other two codes.

Do you have access to a live data scanner? If you do, plug it in and check what temperature the ECT is indicating the coolant to be and let me know what you find.

Next, here is a link that explains the most common causes for a crank no start. I suspect it may not help with this issue, but take a look through it.

Also, if possible I would like you to check if there is both fuel to the engine and check the ignition system for spark to the plugs. Here are two links that show in general how it is done:

Do this and let me know what you find. One last question. Does it sound normal when the engine is cranking?

Let me know.

Hello,

In the diagrams down below I have included the diagnostic troubleshooting flowcharts for Direct Trouble Codes[DTC][s] P0117, P0138, and P0171 for your vehicle. Please go through these guides and get back to su with what you are able to find out.

Thanks,

Good evening,

None of these codes will cause your issue.You need to test for fuel pressure and spark to be sure they are present. Without both of them, it will not run.

I attached the meanings for the codes and the possibilities for you.
