My primera 1800 sport 2001. the OBD warning light was on. Took it to my garage they fitted a new Crankshaft Senser. Re-set obd but it it keeps coming back on they say it is the ecu. If i get an ecu from scrap yard and chnge it will it work. Will the ignition key still start the car with different ecu. Thank Harry

Hopefully i can help..
Do you know what the "fault codes" where they got when they plugged it in?
What other checks have they done bar replace the sensor?
They only said it was the Crankshaft sensor. They replaced the senser and the OBD light was off when I got the car back but came back on again the day after. They reset it again but keeps coming back on. They said it must be a faulty engine ECU. I can get one from the scrap yard for £66 with a months guaranty. So if I buy one can I just swap it with the old one without any problems. Also where is the ECU located is behind the glove box. I dont know if they did any other checks.
Hi not had a respons to the above reply yet.
Hi..Sorry for delay
Depending on the fualt code they got as there are many definitions in regards XXXXX XXXXX sensor problems - they can vary from interupted signal either the sensor or the pick up which the sensor reads - a "wiring fault" maybe more likly from the sensor back to ecu - or a possible timing issue which maybe flaging the fault code up - there is small possibilty the ecu could be at fault but if at all possible if you do have somebody locally that can carry out ecu checks just to be sure it is actually a fault then that maybe the best step forward - if not there are many online ecu repair companys out there if you search google for example and see wether that might be a better option - you will obviously need to remove the ecu itself and send it off in secure packaging "recorded delivery" for testing - some do charge a fee - if another ecu is to fitting then its likly it will need to be recoded to your car and usually this can only be done by a nissan dealer..
