Hey everyone, feeling frustrated with the following codes:

P1172 P1175:

I've looked for vacuum leaks on my 00 Disco but can't seem to locate any issues. Are there any tricks for trouble shooting a vacuum leak?

I just had the wires and plugs done as well as a new MAF to turn off some other codes, those codes went away now the above have turned on.

Suggestions? I really appreciate the input

 

0112 is IAT sensor low level signal. Below what temp should be after engine runs 3 minutes. BUT... the IAT is part of the MAF. So perhaps related to your recent swap out. A scanner will show the temp signal being given, and you can determine if it is "logical" (like about ambient at start).

0175 is rich, vac leaks tend to make "lean" - extra un-metered air.. Perhaps air filter clogged. It is the business of the MAF sensor to provide correct info on air movement, so the fueling can be calculated.

Was MAF sensor replaced a particular brand and model number?

 

I apologize but i put the wrong codes in my original post! Thank you for your time in writing that last post, but the correct codes are p1172 and 1175

Iv had so many codes over the years its hard to keep track of them!!

Thanks again

 

Those codes are engine running rich on both sides. I'd look for air filter, possibly clean that MAF if it wasn't a brand new one.
