My 94 Lumina APV (3.8L) would not start (when warm) - cranked but acted as if no spark or fuel. Mechanic replaced computer @ $350 (said too many error codes to diagnose problem) - did not resolve problem. Then he replaced the camshaft position sensor (CMP) @ $125 - that solved the problem. PB
I'm also having the same issue on my 2005 Chevy Tahoe. The local Chevy dealership stated the error code is a result of a failed front crash sensor. In my case it was Sensor #2. The cost of the sensor is $125 w/ a $100 installation fee.
The error code p1193 on a 2001 Dodge Grand Caravan indicates that the intake air temperature sensor has failed. The sensor can be replaced by unbolting it, removing the wiring harness, and pulling it from the intake.
If an engine light is still on after replacing a fan's radiator sensor in a RFW engine the coolant sensor should also be checked. If the coolant sensor is bad it will send an error code to the car's computer.
