Uninstalled O2 sims and boost gauge, but now car won't start

nj335i · 07-03-2009, 07:02 PM

So, I uninstalled the O2 sims and boost gauge... Stock downpipes are on, but now, I'm getting these codes...

P0123 - Throttle Position Sensor/Switch A Circuit High Input
P0222 - Throttle/Petal Position Sensor/Switch B Circuit Low Input
P1417 - Port Air Relief Circuit Malfunction

The car is trying to turn over, but it won't start... any ideas?

maybe the ecu connections are loose?

Do you know which ECU connections I would have to check for that?

check the large ECU connectors and also triple check the wires you just messed with for the 02 simms, betting you mixed them up.

i've never installed o2 sims but check to see if everything in the ecu is connected right, nothing loose. large and small connector and any other wires you messed with.

Well, I fixed it, but I don't know what I did to fix it. All I did was take everything apart again, wiggle connections, and then WA-LA! Weird... but I'm glad it's all fixed.

Thanks guys!
