Replaced the power steering pump recently and give the local indy original Land Rover O-rings for hoses at the box including which part number goes where, after replacing the pump I used a degreaser to clean every thing from the power steering fluid and a day later saw big leak at the box. Took it back and i noted that he still had the small plastic bags with the O-rings setting on the shelve, but he states he replaced them in any case he went back and fort with the orings put them back on and cleaned things and in the process he took the air intake hoses and also disconnected the MAF plug and was not very gentle to things. before completely reconnecting the hose he turned on the engine to see if there was any more leak. When i came out of the shop i got these three codes P1884, P0112, P0103 and check engine light. I cleared them, truck is driving as usual, with some hesitation after it is warmed up and around 40 minutes of driving. But every time when i turn on the engine even without hesitation I get all these 3 codes. Previously i was getting random misfire codes and 0152, which is one of the oxygen sensor. Now P1884, P0112, P0103 4 times in a row. Should i just clean the MAF sensor or do i need a new MAF sensor.

Thanks

 

You can try cleaning the MAF with MAF cleaner, but my experience has not been good especially when you also have the 112 fault for the air temp circuit.
My money is on a Failed MAF and the best place for a Bosch replacement is British Parts of Utah. Do not use an after market or generic Bosch cause they won't work in place of your old one.
The 1884 will go away on it's own once the MAF is replaced.

 

Thank you mike, got an MAF cleaner, will give it a try and see.
Does 2.5 hour labor @70/h sounds reasonable to you for wire change?

 

Yes, that is about right.

 

I think the MAF plug was not properly connected, it came out very easy, the sensor was clean but I cleaned it with CRC MAF cleaner any way, also cleaned the plugs. I couldn't snap the plug back into place and turn on the engine and got all 3 codes and also P0104. It took quite a bit of pressure to snap the plug into place and than i went to sleep 2:00am, this morning every thing started properly and no codes. Drive to work was fine (15miles) no misfire, will see what happens on the way back.

 

Some codes will "wait" until they have repeated on 2 or 4 drive cycles, then pop back up.

 

One whole day without any code.
I run out of gas and did not know that one gallon was like a drop for the land rover, after endless cranking car still did not start, it finally started after I put over 2 gallon of fuel in it. Surprisingly enough no codes or check engine light. I think that the MAF plug was not properly inserted, I also sprayed the right front O2 sensor and plug with MAF cleaner, which might have also helped. I could not get my hand there to unplug and clean it.
The engine does sound like a disel, so I have to find the cause of that next.

 

That is a good way to burn up your already tired fuel pump. Always stay above 1/4 tank to keep the pump running cool.
As for the noise, that can be major, don't go waiting to find the noise, start today and let us know what you find.

 

No codes no hesitation, drives smooth, so I think the problem was the MAF sensor plug, but it is a litle loud, I am not sure if there might be an exhauset leak at the manifold, causing that sound. I also have intermittent ticking, especially after engine is warm. It is clearly audible when the car is in park and I rev it up to around 2000RPM and than let it go, when the RPM is droping there is a clear ticking and once it has stopped dropping the ticking stops and becomes sporadic.

Any symptoms for failing fuel pump? I cranked for quite some time before the additional gas was added
