Electrical problems continue
Electrical problems continue Well some of you may remeber my post on my 20A Engine sensor fuse blowing and how i pulled the MAF-T and the problem went away. well today the gremlin returned and i have no MAF-T on the car but the fuse still blew when I went to WOT at the track. So I checked the MAF sensor as the Haynes manual stated and every thing was good as in the Voltages. So i went out and A-taped the MAF and everything seems ok but here's my question the Code I get is PO102 the Low fequency one. My logs were at idle around 2400 Hz +/- and they climb to around 9400 Hz +/- @ WOT (30lb/min +/-) w/ the RPM as they should. I read they should be around 10000 Hz @ WOT so would this be low enough(9400Hz) to trip the PO102 code? my next thing to try is to look for a short in the line to the 20A fuse. So any help on my question about the MAF Fequency's would be appreciated

Re: Electrical problems continue As I posted b-4 this fuse also powers the o2 heaters. It is more common for this end of the circuit to cause the short that pops the sensor fuse. Be it the o2 harness, or 1 of the sensors itself.
