MI Light On...

[Zednick666]

... so looks like my 1st trip to Wakefield Nissan - anyone had any experience of them?

 

Don't know what it could be, engine seems to be running smooth, no roughness or juddering, power seems to be there (though I'm toddling around really since the light came on last night).

 

Typical though, just before Xmas and it wants some TLC (Tender Loving Cash).

have you got acess to an OBDII reader, might be someone local with one. might be worth finding out first.

 

or do the engine reset, if gives you the code that way.

 

it might be nothing and just needs the codes reset.

Hi rtbuscuit,

 

Nope i'm afraid I don't know anyone with a reader, but I didn't realise the ECU reset gave the fault code - I'll give that a bash, thanks! Where's it show the code?

 

Is this the correct procedure? (taken from google search)

 

ECU Resetting Procedures

 

Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.

A stop watch or an analog clock with a second’s needle will be useful.

 

Operations Procedures

 

1. Confirm that accelerator pedal is fully released, turn ignition switch “ON†and wait 3 seconds.

2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.

2a. Fully depress the accelerator pedal (HARD).

2b. Fully release the accelerator pedal.

3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.

4. Fully release the accelerator pedal (while the CEL is still blinking)

5. Wait about 10 second.

6. Fully depress the accelerator pedal and keep it for more than 10 seconds.

7. Fully release the accelerator pedal (The CEL light will continue to blink).

8. Turn ignition switch to “OFF†position and now you can start the car. The CEL light should be gone.

 

If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

if i remember rightly when i last did it ages ago i think its at about step 7 it will give you a continuos sequence of flashing lights.

 

and it will repeat the sequence indefinatly untill you switch off the ignition.

 

you'll know when you get to that point.

 

might be worth putting a shout out for someone local who might have an OBDII reader. i have one now but i'm a long way off.

Thanks guys - turns out it's code P0144, oxy sensor!

 

Had to go out at lunch anyway so nipped to local dealer and they cleared the code, booked me in for Friday to look at it, hopefully it's fine though / not a permanent code as it's not come back on.
