  1. OK thanks Trevor I'll try harder to find a scanner. thanks again i'll update you with the result. Simon
  2. OK Thanks Trevor, Just to be clear........ you're saying from what I've told you, you think I should replace my existing sensor (and then I will need to set up correctly) or should I carry on adjusting the existing sensor because you think it's only the position that is wrong and I should continue adjusting slightly each time until it comes right? The Nissan agent did say they sold a lot of replacement throttle pedal units. Like you say I'm also suspicious about the wiring connector because the last time I was adjusting the position of the sensor, I would have been pressing on/moving the wires/connector as there's very little room to work. It went into limp home mode but know I didn't disconnect the connector. So there might be a joint or baynet contact in the block which isn't making a consistent good contact. So when/if I get it sorted I'll zip tie them in position. Thanks again, I'll let you know how it ends. Simon
  3. Hi I haven't managed to get a scanner. I tried adjusting the pedal both ways and one way made the revs increase. There wasn't much adjustment left to move the pedal unit the other way and the little it did move didn't seem to have any effect on the revs. Its like the ECU is detecting a problem and compensating for it all the time as well at start up. Because some times when i'm driving without moving my foot the car shuts of power a little then moments later opens back up to where it was before. Is there a sensor at the throttle body end? Simon
  4. Hi Trevor I'll as around to borrow a scanner and/or try adjusting it. I'll let you know. Cheers Simon
  5. Hi Trevor You were right about the wiring being difficult. No space for probes, so I couldn't get my probes in to be sure I was getting a good contact. Ended up putting it into limp mode. LOL Disconnected the battery for 20 mins and it came back ok but still with the original problem. There are 8 wires to potentially check and I couldn't find which one was the correct one to probe. Do you know where I can get the colour code of the wire I should be measuring voltage at? The only voltages I did find weren't conclusive either, as they varied every time I re measured them which only made me think I'd got a bad earth or wasn't making good contact to the wire with the probe. Cheers Simon
  6. HI no scope sorry. in fact my Pro Scan V580 scanner couldn't connect either! The ODB port is just to the right and below the steering column Yes? There aren't two are there? I have got a multi meter though which should work? Thanks Simon
  7. Hi Trevor No I haven't which is a bit mad as I've got a code reader. Just thought that there was no engine warning light on so there would not be any codes. I'll do it tonight. cheers. Thanks
  8. Hi Just cleaned the MAF sensor with electrical contact cleaner ----- No difference. Obviously it could still be down to a faulty sensor but not a dirty sensor element. Any ideas? Throttle position sensor maybe? Simon
  9. Hi, I've done the air, diesel,oil filter and oil change. No change to the revving problem as I thought would be the case. I did find some thin (3 or 4 mm dia.) steel pipes at the top of the engine around the injectors which are open ended with no rubber pipes attached and I'm guessing this is correct? but what are they for? I also found a rubber pipe (10mm dia) rising from the transmission or transfer box and this was also open ended, could this be a vent pipe? About to clean the MAF sensor.
  10. Hi I'm new here. I have just bought a march/2003 registered 2.2 diesel X-trail 164k miles in need of a service. However I'm still very very! impressed with it all the same. But when I start first thing from cold the engine revs to about 3000 rpm without me touching the pedal. After about a minute it drops to a normal tick over. After this it starts ok for the rest of the day. I've seen threads suggesting cleaning the MAF sensor, replacing the fuels rail pressure sensor and/or the fuel pump sensor. I'm doing the service anyway but can anyone lay bets on which of the above part changes to try first to solve the above problem or suggest another action. Cheers Simon
