Pistol p Posted December 15, 2015 Report Share Posted December 15, 2015 Sounds like a fault on the o2 sensor. It's on the catalytic converter. Replacing the sensor can sort it. Quote Link to comment Share on other sites More sharing options...

beerdeor Posted December 16, 2015 Report Share Posted December 16, 2015 Hi Its a deisel so doesnt have a cat as such....your fuel temp sensor is on your fuel lines in the engine bay normally a 2 pin red connector on it I assume you have a lack of power hth Jim Quote Link to comment Share on other sites More sharing options...
rjimmer Posted December 16, 2015 Report Share Posted December 16, 2015 I bought a (54)Partner van about 7 years ago and after a few months it would not start soon after stopping the engine, but was OK after about 2 hours. Someone told me to disconnect and reconnect the battery so that the computer rebooted. I didn't want to do that because I had heard that could cause other problems. People were telling me all sorts of things that it could be. It had been unused for a week or so and when I tried to start it there was a 'grunt' and all the ignition lights went out and the battery was flat. I started it with jump leads, took it to a garage, leaving the engine running, and they thought it was worth trying a flywheel sensor, which they ordered. I drove it home and it has been starting OK ever since(till it was written off in an accident), leaving me with a spare un-needed flywheel sensor. SO! Try disconnecting the battery.

littlerob Posted December 16, 2015 Report Share Posted December 16, 2015 Clean the egr valve might be sticking or partly carbon uped can cause fuel and O2 n several other sensors Quote Link to comment Share on other sites More sharing options...
pestcontrol1 Posted December 16, 2015 Author Report Share Posted December 16, 2015 Clean the egr valve might be sticking or partly carbon uped can cause fuel and O2 n several other sensors iv got egr at the top of the list for friday morning din"t think it would cause them type of faults thou lol Quote Link to comment Share on other sites More sharing options...
Bad Monkey Posted December 16, 2015 Report Share Posted December 16, 2015 Hi all i have a fault on my van and its doing my head in the code is p0138 fuel temp sensor A circuit high input ? but i can"t find much out about it like Where it is How to fix or what it is Dose anyone have any ideas plz Cheers PC1 P0138 is an 02 sensor circuit high code! P0183 is a fuel temp circuit high code. The easiest, quickest and cheapest way to sort your problem is to find a REPUTABLE PROFESSIONAL DIAGNOSTIC SPECIALIST. Trust me it's gonna be much cheaper and less painfull than following the **** being passed off as help in this thread so far, however well intentioned it may have been. There is absolutely no point throwing parts at a problem if no attempt has been made to identify the root cause. Is it the sensor? wiring? ECM? excessive fuel temp caused by excessive fuel pressure or some other fuel system fault? fuel cooler fault? I don't know without carrying out a thorough diagnosis so there's no way anyone else on here will know either. Quote Link to comment Share on other sites More sharing options...

My fat fingers and i dint see it the code is P0183 fuel temp circuit high i have had it in the garage twice now with no joy up to now but i have noticed this last few days that its not as good on fuel as it was for some reason i dont know Quote Link to comment Share on other sites More sharing options...
subsonicnat Posted December 17, 2015 Report Share Posted December 17, 2015 do not know the car,but, if it is diesel,, Check over flow pipes, and all connections to fuel lines, even the one from the tank RUST. if there are sensors involved, just like the old engines of Yor, take sensors off one at a time, I did on a blokes turned out it was oxygen sensor on inlet manifold, if it doesn`t change the way its behaving keep pulling them off. check for air or water in the fuel filter bowl, always worth cleaning anyway..

A clue is given in the fault description that everyone is overlooking! Often a fault code is not implying a sensor is faulty! It is telling you the sensor has detected a fault!

Bob on, howeverfinding someone as estute is not so easy! A clue is given in the fault description that everyone is overlooking! Often a fault code is not implying a sensor is faulty! It is telling you the sensor OR ECM has detected a fault, Best reply so far! Edited December 18, 2015 by Bad Monkey Quote Link to comment Share on other sites More sharing options...
Underdog Posted December 19, 2015 Report Share Posted December 19, 2015 I ask for the test data for a component. Any strange looks I walk away! Had some fun with a Suzuki dealership once. Made them dig the data on an o2 sensor, tested the old one and oh look in spec. Got my money back! They should not of spoke down to my wife!
