Engine code 108-4 air pressure sensor
Well looked at the old post and no updates soooooo
I’ve got a really low time buss 2002 10k on her replacing fixing a lot of silly stuff
I can go on ...
Any way check engine light is on check code and it’s a 108-4 which is the ampnient air pressure sensor to high of voltage 108-... the 4 means a short some where.
Replaced a Cummings sensor $80 bucks , didn’t fix it . Went back to Cummings they said normally they replac rhwas pig tail to. It is what usually shorts the sensor....?
Anyone else have some input ?
Like I said replaced sensor am going to intal pig tail
