My 65 plate Landie 110 went into fault mode on Saturday and first suggestion was a faulty Mass Airflow Meter. Land Rover Assistance who were great and suggested that this code is rarely an MAF fault and is more commonly an issue elsewhere. In my case the dealer identified water in the air intake system as it was missing an essential seal and it had caused a sensor to be damp. The fault code was still there. They eventually located it to the wiring to the MAF sensor that had worn through and was shorting. This may require a new loom! Just thought I would mention it to those who have repeating MAF fault codes occurring. '65' plate Defender XS 110 Station Wagon

A common one on the Puma fitted engine.
99% of the time it's one of two wires that rub through on the main loom from engine to ECU. Transits suffer badly from this, I only did one last week. If it is the wires? it's fairly easy to test and locate the break, and a simple fix...  80" 80" 86" 88" 90"

Well they tell me they have repaired it, which I assume has not required a replacement loom. I would be intrigued to know where it exactly had worn through '65' plate Defender XS 110 Station Wagon

Can't hurt to ask them to show you the repair and ask what parts they have used?
Also, if it's worn through the loom once, have they done anything extra to prevent the fault happening again? |

If they had found a fault in the loom it would be very easy to spot.
Look for new cable ties, fresh loom tape, or electrical tape. Usually they break in the largest part of the loom around the top of the engine. So you have to open it right up to find the wires. If it has been done like they say, you will see evidence... 80" 80" 86" 88" 90" Wanted, Forward Control Anything considered. |

2013 110 PUMA 2.2
Have had several MAF faults. When the vehicle was still relatively new, I noticed that the insulation on each of the four wires of the MAF sensor is cracked and the bare wires are exposed just where the the wires enter the connector. See photo. At the time I put it down to poor wokmanship and didnt dwell on it for long. I'm guessing now that this may be the cause of the faults I'm seeing (tracking between conductors perhaps?). On the last occasion, the engine went into limp mode and the engine light came on. I moved the harness and on the next start everything returned to normal (no warning light, no limp). Would you know if it is a simple task to remove/install the wires in the connector? There may be enough slack in the harness to allow me to reterminate the harness. Do you know the PNs for the connector alone and for the complete harness? Thank you.  Click image to enlarge |

Think Martin sells that in the defender2 store the connector. Searching for my first Defender...and started just as Covid hit, so talk about timing.
5 months after starting the search I found it, and here is the details |

I did this repair a few weeks ago with a pre-wired plug from Martin. Details here:

Thanks Race.it, thanks LRA! Great information. Appreciate it. Do you have a PN for the pre-wired connector?
