I got a roof condition P0172

It’s definitely running rich ive trown numerous parts at it but I can’t solve the issue. Any suggestions? p0172 is only code

 

You checked your operating temp?
Your TW Sensor reading?
Map Sensor reading?

Oh, I will check it. The temperature seems to be running normal on the dash gauge about 200 to 95 on dash coolenant temo, but I’ll check that TW on my scan tool I don’t remember checking that definitely something to look at. Thanks a lot for the reply. I’ll keep you posted.

 

P0, 172 is the only code and it is rich. Usually a other associated systems will/maybpop a code to give guidance but I’ll definitely check that thanks a lot and I’m going to check the fuel lines too

 

Map sensor is reading but it’s not OEM. It’s a cheaper and a off brand sensor may be better off ago with something more high-end or OEM, When I unplug the map sensor, the truck shuts off, you the old junkyard test but that does not necessarily its calibrated correctly I guess

 

I do appreciate the reply and all comments, I appreciate any ideas thx so much

 

I remember changing the valve cover gasket that wiring harness going to the TW got stretched possibly, it it’s on the back of the engine, very hard to access, moving the harness around to get to the valve cover bolts I could’ve pulled wiring loose or made it intermittent. but I can check It was a scan and should give me some good info. Thx again

 

Now that you have fired the parts Cannon so many new unknowns may have been added to the equation.

There are many threads that discuss trying to repair this PO code.
