Lambda Light Illumination Advice (1995 2.0L 10V)

Apr 28th, 2003, 20:42

I have trawled this message board, and identified that my Lambda Light has illuminated today!

I was wondering if there are any things that I could check out and possibly rectify before I take the expensive step of approaching a dealer?

Colleagues at work have suggested removing a plug near my cat and blowing out the sensor?

Does that sound sensible? Or should I drive myself to a dealer and find out for certain?

I knew a good place for Volvos in Cardiff, but haven't yet found a recommended place near Wolverhampton - any suggestions?

All the best

You really need to read the lambda code.
If you have the OBD11 type connector just in front of the gearstick, then there was an LED circuit on posts a while back (about Jan 2002) that certainly works for the 10v 2.5l fenix system to read codes..which I believe the 2.0l 10v has...if you have the underbonnet LEDs then it's simple.
Otherwise it'll cost just to read the code...could be throttle housing/oxygen sensors/all sorts...

Sorry, but I'm not at all familiar with what you're talking about. Underbonnet LEDs? Are there a couple of links that I could look at for info on how to work the codes out?

Sorry if this is a daft question (or covered well elsewhere). I'm an experienced aircraft technician with bugger-all knowledge about cars!

Firstly check all vacuum hoses etc. around the inlet manifold/throttle/air filter area, you might need to remove the cover over the throttle mechanism. Listen for any sucking noises coming from that area and replace any cracked hoses.

OK - Finally I found the reqd info at volvospeed and have checked my fault code.

I got 2-4-3

Have reset the light and gone for a short drive with no fresh illumination so far.

Any ideas on what it might have been?

With thanks

2-4-3 is Throttle position sensor signal out voltage range.

When I bought my 850 I had this code so they cleaned the throttle housing and sensor...all ok after that.

Excellent - cheers.

I shall look into it and see if things pop up again
