i have a 2.5 v6 and the timing belt snapped and wrecked the engine. i got a 2.6 bare engine and changed every thing from my 2.5 on to it and fitted it. its messing about going then stopping again and was wondering should i use the 2.5 sensor because the brain is 2.5 or the 2.6 sensor because of the engine? cheers

[omegod]

Don't know the answer but have a 2.6 ecu and chip/ key set for sale if needed

[05omegav6]

2.6 sensor assuming same number of wires might need a tail of loom to connect it as the plug might not fit

[biggriffin]

If the 2.6 was undressed and you redressed it with all of the 2.5 sensors,it should run. Only problem would be the Sai system as a 2.6 dosnt have a egr/sai system.
 so i would thing your crank sensor on the way out..

just keeps putting up hall sensor high voltage? any thoughts

[biggriffin]

Crank sensor,knackard

[Kevin Wood]

"Hall Sensor" is the camshaft sensor, not the crank sensor, if memory serves, although neither is actually a Hall sensor.

Can you get the numeric code from the code reader, as I suspect it's just giving you a generic description?

Crank sensor is P0335. Cam sensor is P0340.

You can just do the pedal trick to verify this.

[05omegav6]

Could be a compatibility issue... Car built as a 2.5 which went bang. Engine replaced with a 2.6 lump running 2.5 sensors and management. Pedal trick won't work, paper clip might

[Kevin Wood]

Yes, of course, it'll be the old management so paper clip test.

[husky12]

paperclip test?

paperclip test?

You should use the sensors that match the ECU you are using.

Crank sensor wiring runs close to the exhaust manifold and goes brittle in use. It is quite likely that yours has failed as a result of being disturbed.

A faulty crank sensor doesn't always bring up a code. Both the failures I have had gave no codes

[husky12]

i am using the 2.6 crank sensor and is starting and idling fine now. the  3 earths at back of engine had came lose somehow.now its starting but wen you accelerate its missing an choking like mad, and takes a wile to build revs. if you slowly accelerate its dosnt seem to be ass chokey  but still misses, im gonna read the codes tomorrow but any ideas?

sounds like a idle valve or throttle position sensor

No ICV on a dbw engine
