My Engine Managment Light Is On :(

[grease monkey]

I went about 12:30 and got some fuel in my car, texaco high octane stuff, 97ron me thinks, then the guy wouldnt let me fill my tank, because they had some drive offs well i was quite annoyed because 2 guys drove in whilst i was argueing with him saying "i dont know how much im putting in so ill fill the tank then come and pay" still wasnt good enough, so i put £30 of this fuel in

Then drove to a garage dowen the road and put bp ultimite in, and other £45 in the bop garage, then i went for a lap of town, half way round the town

My engine managment light came on!!! :( dont know why the car isnt down in power or anything, of any slower, so im unsure!!! Can anyone help me????

Thanks :) in advance

u need the fault code read otherwise its a pure guess

[grease monkey]

Is there a pin out test i can do???

[Rob]

yes u can do a test by shorting the pins out but TBH its a pain in the butt and is not that easy to read the flashes - dont know which pins to short at the moment tho

You could reset your ECU and take another drive. The light might stay off but just take note of what the car is doing if and when it comes on again.

It might not tell you anything more but it is easier and quicker than the pin out thing.

if you disconnect the Battery for 3 mins that will re-set the e.c.u.You may find an issue with one of the oxygen sensors is your fault,common problem and gives no loss of power or driving pattern as you have discribed.Only a guess, as like the other chap said you need the codes read to get the exact answer.

Im a mechanic myself and this is baffeling me!!!!!

my dads carina eml has been on for 3 years now. nothing wrong at all. pulls fine. my previous primera eml light came on, again nothing wrong at all. the primera i had after that had a light on(caused by head & system).... wanna guess? nothing at all wrong!

Surely if you are a mechanic you must have (or have a friend with) access to an OBDII reader ?

[grease monkey]

:):) i had an OBD reader LOLLOL what a *****, anyways turns out it was a problem with the cat, i cleared the fault :) and now its ok :P:P
