I remember seeing BrosFourSpeed on YouTube check a code on the fly and found it was his HFC and was able to clear the code too. Sounds like they want your money.

Please do not ever say a code reader will pinpoint exactly what is wrong. All a scan tool will do is give you the issue the pcm is seeing and what area the problem is in. This is where knowledge and diagnotstic techniques kick in to do testing and troubleshoot the sensor, wiring, signal etc. This is what separates a true tech from the parts changers. From his story it sounds like he has already been hit by the parts changers and this second shop sounds like they are ready to start throwing more parts.

Op it's time to find yourself a reputable shop that will actually do diagnostics, and don't expect it to be free or you can bet you've just found yourself another parts cannon shop.

"...what area the problem is in," is what I meant. "...don't not..." Is a double negative btw. Thanks for the correction...

Well apple helps me make all kinds of mistakes and proof reading on a 5c is a bit of a challenge.

Don't throw money and parts at it. Get the codes read. Autozone does it for free, as has been mentioned.

Khanxyz0z · 04-09-2018, 04:09 PM

nissan read the codes,
even they said its like 3-4 of them
mass air flow
throttle bodies
some minor ones from engine.

they said if you want all the code areas changed, its gonna be 4-5k. im like that is a set of new pss, nice rims, and other upgrades.
i kind of just want to change whats causing the light to come on, not spend a fortune on things that are not eveb going to get the light off
