Question about 2005 Land Rover Range Rover
I have a 2005 range rover that had check engine light on . I hooked up obd and got code p2a00 which was 02 sensor circuit range/performance bank 1 sensor 1. I had changed the passenger side front first and nothing changed. I was told that bank 1 sensor 1 is the driver side, so i ordered another front sensor and changed that one. Nothing changed. I noticed that when i start the truck in the morning is sounds great ,but a minute later it sounds and runs horrible.Any suggestions what else to check. Thanks Moe

Almost certainly blend motor failure. The heater matrix has several blend motors which divert hot or cold air the vents you select. The problem is, the buggers fail. Their £200 each and a nightmare to get to. Unless you actually want to remove your entire dash i suggest you put up with it. I understand a garage will charge about £1500.

This might sound odd, but it could be the gearbox output shaft bearing. If the transmission sounds noisier than it did, this could be the issue. Only way to check is to take off the transfer box. Not a major job, but takes a while. Some good fault code readers will read transmission codes, and allow you to see in real time what the sensor is doing - if the sensor suddenly loses signal, then it is very likely to be the a bearing (output shaft bearing most likely) that is at fault, causing the sensor ring to move too far from the sensor. Best guess, but could be other things, so don't go taking that transfer box off without getting a road test with a good fault code reader on it - or find someone with a portable oscilloscope and put that across the sensor - you should be able to see nice square wave pulses - if they get bigger and smaller (variable amplitude), that's your problem. If not, the fault lies elsewhere.
