Check Light?

[Bovien 6]

Anybody know what the red 'chek' light (the top, right one) means?

 

I have a feeling it is related to he cat (mine is a 89, 1.9), as the engine has been changed and now the lambda sensor as well. Is there anything else down there, or what am I missing? Once in a while it can blink at startup and then not be on until the engine is restarted...

It can mean various things - a sensor fault, throttle switch shorted out, lambda.

 

Does it come on and stay on, or just blink once when you switch on the ignition?

[Bovien 6]

Always on (except for VERY rarely as described)

 

Everything works, MOT'ed, complete engine change and all. I dont get here it can be

Have you checked the code(s) via the two pin diagnostic connector to see what the ECU has stored?

Quite often it's the Valve that takes the fumes to the carbon canister, Not allot else lights the light up

I had this EVAP code (solenoid purge valve) for quite a while on my Motronic car .. it reappeared every time after starting the engine and by bringing the revs up above 2000rmp , engine stumbled for a second and the K light lit on and was on all the time during the driving or if left idling afterwards .. haven't noticed any issues while driving , all seemed fine bar the K light permanently on .

That sounds SO right, as the canister (and fittings) haven't been changed. The bottom if the canister is literally gone due to corrosion (the only on the entire car). So, I'm guessing Ill just follow the tube from the canister (don't remember how it is connected) to find a valve and a sensor? Would I be able to disconnect or short it out?

You'll need to fit a resistor to emulate the coil in the valves relay.

[Bovien 6]

Makes sense. Any way to figure the resistance rating?

[MikeC 10]

try a variable resistor to find your resistance required. I would assume it would be a 4-20 mA signal

[Ryan 99]

200-400 ohms should do it.

Thanks a bunch guys!

[DamirGTI 323]

Fitted 1.2Kohm resistor on mine and it did the trick ..

Even better! I'll see if I can get one tomorrow. You don't have a pic of the install, do you?

[Bovien 6]

1.2kOhm worked perfectly. Thanks!
