Limp Mode / Engine shuts off during idle

Alpine335TT · 08-29-2009, 10:13 AM

Driving home last night I got a limp mode. Normally if this happens I restart the car and it goes away, however this time was different. I got home and here are the codes I read with my scanner:

2abc Charging Pressure Sensor - Electrical

3100 Boost Pressure Control Deactivation

2F08 Inlet Air Temperature Sensor

I tried to clear the codes but they wouldn't actually clear out so after repeated tries I called it a night. This morning I went out to the car in hopes that it would start up normally. It started up yet again with the limp mode and even beyond that, the engine just shut off by itself for no reason. This happened a couple times.

Can any of you offer any advice?

I am running JB3 1.22

Thanks

Pull the JB3 and see if it reoccurs. It sounds like there may be loose connections as both those circuits are touched by the JB3.

My car was in limp mode and the engine kept cutting out and I couldn't figure out why...

Terry responded to my email within minutes and helped me diagnose the problem... the chargepipe blew off and the tmap sensor disconnected....

Problem fixed.

Thanks Terry!! Amazing Service!!

Good point, a loose TMAP would cause that issue. Glad to hear it is resolved.
