v6

[D_a-RR-e_N]

my ecu light is on in my corsa ive flashed the codes and they are the following
16 - which i think is the knocksensor 1 (where is this located??)
13 - oxygen sensors (ive got a wire lose i know about)
31 - RPM signal ( crackshaft sensors) ?

would a dodgy oxygen sensors cos any of these or not ? (apart from 13)

[D_a-RR-e_N]

does anyone know where these sensors are?

[RobbieV]

Is this a V6 engine then ?

Code 31 will show up when you're flashing the codes with the engine not running.

16 is the front sensor IIRC

I have been trying to fix this on mine code 16.

Have been suggested to wd40 the contacts, and reconnect. There is a known fault in the wiring loom for this sensor. Will be putting mine back together later this evening, fingers crossed.

This website will show you all you need to know about ECU faults, codes and sensor locations [img]/smile.gif[/img]

Also, make sure its torqued up to the exact correct torque setting - they're very delicate in the way they work so it has to be spot on.

You're right though, the wiring gets screwed as it runs over the engine, gets hot, and breaks down.

where is code 16 (knock sensor placed on the engine then??

ecu light stays off untill i rev it up then comes back on any ideas ??????

thanks guys ......

[RobbieV]

If you look at the website all the info is there, Fault code 16 is number 1 knock sensor which you can see on the pic [img]/smile.gif[/img]

[callymental]

Mine is showing signs of being fixed with a little wd40, not convinced yet, but will have a decent run tomorrow.

spot on ill have a go at cleaning it up and hopefully may come out of limp home mode ! and i can have a go and see what the motor is really like...
thanks alot

[D_a-RR-e_N]

no go tryed cleaning it up and it ticks over ok, but as soon as i put a bit of throttle on the ecu light comes on again. if i get a new knock sensor willl this solve the problem ?

[D_a-RR-e_N]

are they the same as vectra or anything else ?

did you disconnect the battery for 1/2 - 1 hour after you cleaned the connection, you need to do this to clear the fault code, try it after you have d/c'd the battery to make sure before you go ordering new sensors

[D_a-RR-e_N]

does it half to be 30mins cos i have discontced ecu every time and ecu light goes off untill i rev it up again.
