Hi. I have a 2007 LR3 SE 4.4L. I just changed the right valve cover gasket and spark plug well gaskets with no issues.

I had the MAF disconnected with the airbox out, the wiring brackets off, some VAC lines off...all the stuff to make more space. After I was finished and started the engine again, I had a whole laundry list of faults, similar to having the MAF disconnected. It seems like I have 2nd and 3rd gears and the engine otherwise runs fine. The car has 300000 miles and everything is pretty brittle. Could I have broken a wire somewhere? Thoughts from the masses?

Engine
-P0102: Mass air flow circuit low input
-P0113: Intake air sensor 1 - circuit high output
-P0198: Engine oil temp sensor circuit high output
-P0513: Incorrect immobiliser key

Transmission
-U2023: Control Module network signal calibration data.....

Vehicle Dynamic
-U0401: Invalid date received from ECM/PCM

Dashboard
Transmission Fault - Limited Gears Available, HDC, etc.

Thanks. Tim

 

Clear codes and check again, but it looks like an MAF issue. The MAF also contains the air intake sensor. The oil sensor fault is odd though. The key one, I get that all the time. The others may just be ghost codes that may not show up after cleaning except trans, but that can be MAF related.

Pull the connector and make sure no pins pushed back into it, etc.

 

Never mind. I’m an idiot. Turns out it was two separate things…both my fault.

I didn’t press the MAF plug on tightly enough and it tripped all those related codes. I was also messing around with the oil cooler and forgot to plug that temp sensor back in.

doh!

 

I will take being an idiot over a real issue any day when it comes to Rovers! Glad you got it sorted.
