CEL error 45 update.
 

For a few months now I have had a CE light come on, I decoded it as error 45 (atmospheric sensor fault) - replace ECU.

I opened up the ECU only to find no atmospheric sensor board in the ECU (unlike the USA versions).

So figured that the fault lay elsewhere - the B67 pin 9 connection in the ECU was not connected to the wiring harness (this is where the atmospheric sensor lead goes out somewhere).

So thinking to myself the only sensor that senses atmosphere is the MAF....so bought one from www.jauce.com for NZ$50

Fitted it today - now no more CE light !!!!!👌

Now I want to split open the original MAF and look around to see if there is a broken connection, is there a "how to" doc on opening up an SVX MAF somewhere.

Is this the guide you are referring to?
