my engine light just went on..and im new to the subby world so im not sure what to do.

i got these codes:
P0500 Vehicle Speed Sensor
P1518 Starter Switch Circuit low input
P1591 Neutral Position Switch Circuit low input
P0131 Front O2 A/F Sensor Circuit Low input
P0132 Front O2 A/F Sensor Circuit High input.

if anyone of you guys that got these codes..what did you buy and replace...i just got the V2 CObb AP and its started to give me these codes. IM not sure if its that or its just my subby is getting old and it needs these kinds of maintance..thanx!

 

I'm willing to bet that you connected the two green plugs together under the dash when you used the AP and then left them that way. You have to unplug them or the ECU remains in a diagnostic mode with a flashing CEL and you'll get those codes.

 

nope not plugged in..and its doesn't flash heh..only when the AP is connected..right now with nothing connected. the CEL stay clearly on. thanx tho.

 

Sounds like a wiring problem. Double check connections, did you install any other electrical besides connecting the AP? Like a turbo timer or something? I used to get a misfire and following codes as well:

P1518 Starter Switch Circuit low input
P0131 Front O2 A/F Sensor Circuit Low input

My problem was solved when I uninstalled my turbo timer and reinstalled it. Just a thought, keep your connections.

 

hmm...i do have a HKS turbo Timer on it..and to think about it i did have a misfireing CEL before too on all the cyclinders. but there wasn't a problem up until i install the CObb AP
