Thread: Exessive MAF voltage and high TP with engine off

Hey all.

I got a slight issue. MAF voltage is exessive with ENGINE "OFF" and KEY "ON". I'm at .7volts and TP is like 28

If my memory serves me correct MAF voltage should be .3volts, which would also make the TP alot lower


Can someone verify me maf voltage with the car off and key on

My maf must be on the outs UGH

if not im not sure why this would be higher than normal, bad ground (i though i had great grounds and also have the extra ground wire going to the intake manifold)

Ideal SR20DE MAF voltage should be:
IGN ON: 0.5V (Anything below 1V should be fine, the ECU learns the lowpoint after time)
Idling: 1.3-1.7v (If below 1.0V, replace!)

You MAF is probably fine, but do post the Idle voltage!
Here's my CG10DE engine idling (almost identical values for it):

EDIT: You running an N60 MAF? Here are a FSM specs

MAF: N60
Car: 1991-1994 Maxima
Idle Voltage:1.0V-1.7V
