Hi all

Can anyone tell me which relay is the secondry power supply relay as I think it is messing me about with untold faults and codes.

Cheers

What car is it for? If you can do a paper clip test on your car that will tell you what fault codes are present.

Secondary power supply relay ..... ?? You'll have to describe what it is you think you want to find. I've never heard of one on any of the car's I've had.

Secondary Air Injection relay?

Hi
Omega 2.0 estate 1996. After the paperclip test I have the following fault codes

0505 idle air control voltage high/low

0110 intake air tempreture voltage high/low

0100 Mass air flow sensor votage high/low

0340 Camshaft sensor incorrect signal

1230 Power supply relay sencondary circut votage low

I have changed the cam sensor/air flow meter/crank sensor.

I may be wrong but it all apears to be due to low votage coming from a relay. If anyone can help. :-/

Do you currently have EML on ? if not good, if so what symptoms are you/have been experiencing ?

Starting ok when cold. Once you switch it off it won't start again, it tries to start (a bit like the older cars when they were flooded). It will go if you persevere but it's a hell of a job. Then the light comes on. If I leave it for a day it will start normal. The car is very sluggish like towing another car. I have checked for sparks on all cylinders.

I believe the secondary circuit is joined to the main relay, its just like half the circuit controlled by the main relay looking at a simtec diagram this looks like that's the case if that's any help.

I believe the 0110 air temp sensor is known for stalling the engine

Everything else has been changed, if you have the time and patience start, stop and start the car 20 or so times and check the codes again as if you have corrected anything the ECU will clear them when its satisfied the error has gone, maybe that will give you a better understanding.

Sorry i cant be of any more help, that's what i would do.

Sounds like cam sensor, and the 0340 confirms that

Thanks for taking the time to reply all. I will try all of your suggestions in the morning...weather permitting

Much appreciated

I'd go along with that too
