Dieselfixer Posted July 29, 2013 Share Posted July 29, 2013 Hi All I have a 96 CH613, 427, 13 speed and I have a elect. malfunction light on and a code 2-2. The dealer said it is boost pressure sensor but they say this truck does not have that sensor. I looked all over the air intake system and I don't see anything but a air temp sensor. Anyone ever run into this problem or have any ideas on it? Thanks.

turckster Posted July 29, 2013 Share Posted July 29, 2013 B/C faults 2-1 and 2-2 are coolant temp faults, the sensor is located at the rear of the water manifold-pointing twards the cab. this b/c is the same for VMAC I or II. B/C 2-2 is voltage above normal or shorted high. Could possibly be the sensor itself shorted internally or wiring issue. good luck.

Dieselfixer Posted July 30, 2013 Author Share Posted July 30, 2013 Thanks Turckster, The dealer was telling me 2-2 was for boost pressure sensor and I would need to bring the truck to them to be hooked up to the laptop to find the problem. I will try changing the temp sensor. I just finished doing the oil cooler and flushing the cooling system a few times to get the oil out of it so there is a good chance the oil in the cooling system may have caused a temp sensor failure.

staxx Posted July 30, 2013 Share Posted July 30, 2013 Follow the wire harness over the back of water manifold , they are bad for rubbing threw the harness back there.
