Hi, just wondering on the power fc commander whats the abbreviation for PGS and ICW, I think ICW could be intercooler waterspray just need confirmation. Its just that PGS is flashing intermittantly when driving and shuold the exhaust temp sensor be reading 5.10 volts all the time. If the reading is wrong could it cause a running problem. My car is a v4 sti
Cheers

Anybody please!

 

PGS? Can't think for the like of me what that could mean Are you sure the little LCD isn't displaying 'PCS'?, for Purge Control Solenoid? Just a thought...

 

It is ICV which is the Idle Control Valve and it is PGS but joz you are correct it refers to the purge solenoid.

Cheers for that so its the purge solenoid just cycling on and off. What about the exhaust temp voltage should it be reading 5.10 volts?

bttt

 

any help on the exhaust temp voltage cheers

 

it doesn;t record exhaust temp so which abbreviation do you think is exhaust temp?

 

Cheers for the reply JGM. EXTM is reading 5.10 volts, sorry i thought it was exhaust temperature going by the abbreviation. Its the bottom left one in the sensor voltage page.

it has been said to be exhaust gas temp in the past but the ecu does nothing with exhaust gas temp and I don't believe it is used.

I tihnk it is just a dummy value and carried over from the other powerfc models etc..

Thanks for the help JGM, i thought i had a dodgy sensor but if its not used thats ok, I thought it may have been the cat on fire sensor or whatever its called thats in the downpipe?
Cheers

powerfc doesn't use it..

 

bttt

did you find out if the PGS should be flashing on the commander?

 

yes it is the purge solenoid and it is suppose to click on and off etc..
