Title: Maf sensor problem?
Post by: JamesV6CDX on 05 September 2007, 19:49:33
Fault code 73 - Air Flow Sensor (AFS) Low voltage is stored.

Presume this is the MAF sensor?

Pointing to a dodgey sensor?

Check the connectors first - also clean the sensor - search for the correct gunge.

What air filter does it have?

It's hard to tell, when all you have is a paperclip ;)

It flashes out the code, but no EML light on.

Ah, good point.

How do you know there is no air leak, you had a vac gauge on it?

I've not been able to go that far, I've only been able to check the obvious so far, with limited resources.

A vacc gauge would be a great addition to my toolkit, where do you recommend getting one?

And more importantly, who's going to write the how-to on using one properly? :D
