hi all any help would be great firstly after reading on here for sometime i have changed the cam sensor genuine vx,coil pack,maf sensor,and still had the light coming on but car it self was behaving but the light was staying on so i took it onboard to change the crank sensor now the car has gone into permanant limp mode since ive changed the crank sensor,i have 4 error codes on machine 2 for gearbox, crank sensor, and rpm signal any advice plz

Right, just cos youve changed parts, it doesnt mean they are working, new does not guarantee that unfortunately.

Youve changed a lot of parts, and therefore added a lot of unknowns.

The main sensor to cause grief on the 2.2 is the CAM, which also throughs up other spurious codes all too often.

Do you still have any of your old parts to try swapping back with?

Do you have your own computer, or using someone elses?  be nice to clear all codes and start again.

hi there jimbob i have cleared all error codes with obd machine the problem seems to be since ive fitted the new crank sensor i have also been told that the atf in the gearbox could be low and that the selector switch could possibly do with a clean is this true the cam sensor is a genuine vx one fitted as advised i do have the old crank sensor and cam sensor when i brought the car the eml light and the car and spanner light was on i fitted the new maf sensor and the eml light went out if that helps

Right, you`ve cleared all the codes. Have you started & driven it a short distance to generate a "present" code (as you say it`s in limp mode)

[alan36]

hi rob i cleared the codes as soon as i start the car the light comes on and it goes straight into limp mode

[RobG]

So have you checked for new (present) codes?

[alan36]

i have crank sensor code,rpm signal code,and 2 p1700 codes

[alan36]

the car is out front and i have the code reader here would it help if i get the codes quick and post them to you

Refit all the original bits and start again. Were the parts you fitted genuine Vx parts or aftermarket?

Where are you?

[RobG]

Right, you need to double check all wiring & connections on cam & crank sensors. P1700 is a service request for the autobox. Ideally you need to get box codes read as well but an ATF check/change would be a good starting point

[alan36]

the cam sensor and maf sensor are vx the crank is aftermarket

[alan36]

rob ive checked all wiring and it seems to be fine cleaned all connections etc,the problems have got worse since i changed the crank sensor

[Proz]

When my cam sensor went i had the P1700 as well ... something about " MIL request from Transmission " or something along those lines , cant remember what it was exactly but that went when i did the cam sensor ... is it a possible duff sensor  :-/

Because it`s aftermarket (normally crap). Stick the original one back on and see what happens
