OKIERX-7

OK, I got code 13(pressure sensor) the other day off my T2. I did the FSM test and the results were 1.7 volts @ 3-3.9in/hg. The FSM says it should be from 1.9- 2.4 volts @ 3in/hg. I'm a little out of spec. Should I be replacing this sensor now or is it close enough?



Please a little help, thanks

you disconnected the FCD right ?

OKIERX-7

Heh. Yeah, I disconnected the FCD. Actually with the FCD attacthed I get 2.2 volts@ 3.0in/hg. But my first reading was with the FCD taken off.

i have a better question are you having any problems ? if so leave the pressure sensor alone

I don't even know what the point of the pressure sensor is besides being a pain. The ECU uses the input from the air flow meter to determine how much fuel to give. So what exactly does the ECU adjust according to the pressure sensor readings, besides fuel cut?

I think it has something to do with the ignition timing retard/advance. I've been having a high idle problem that's why I'm concerned about it.

Maybe I'll check the manual to see if they say anytyhing about it...one of these days.
