Disco 2 Holding revs between gear changes

Charlie Charles · Sunday at 13:48

Hello all,

My p15 manual Disco 2 suddenly started to hold on to revs in between gear changes. I have been led to believe that this would be caused by the clutch switch. I unplugged the clutch switch - no difference. I bridged the pins - no difference. Does anyone have any other ideas, please? Thanks.

Hi, it's possible to be something on that circuit, the best would be to plug in a nanocom or similar to see if the ECU gets the signal or not but if you can't get hold of a scanner check with multimeter if you have earth on the plug's black/green wire, if no earth splice into that wire with earth from a close point, if it has earth connect a piece of wire to body and insert it to the black/white wire in the plug, according to the result we'll speak again

Thank you SF, I'll have a look at that as soon as I can and report back.

In addition, if all these tests are failing check continuity of the black/white wire from the plug to ECU black plug pin 35

OK, I'm going to admit my stupidity - publicly! I didn't bridge the plug, I bridged the sensor! :vb-groan2:

Funnily enough, it works just fine now! Thank you SF. Out of interest, did you learn your English from chatting on here? Your English is incredible.

Welcome. Maybe the plug was not connected well then, I'm glad it was so easy... aamof i learned English in high school first then trained myself in many ways
