Question about 1991 Chevrolet Lumina
I drive a 1991 3.1 Chevy Lumina. Three months ago I replaced the Power Steering Pressure Sensor Switch because the car began to stall out when I would make turns, and eventually completley died. Today my car is dies every time I make a right hand turn, regardless if I have let the car "warm up" or not. Any ideas what it may be??
DTC - 22 Throttle position sensor error (signal low), is tps connected?
DTC - 23 Intake air temp sensor error (low temp indicated) check and make sure the sensor is connected
DTC - 43 Knock sensor error, ignore this for now, will not cause rich run.
DTC - 53 System voltage too high, check reference voltage from PCM, it should be around 4.5 Volts, this could be the cause of all your problems, the computer will need to replaced almost for sure.

SOURCE: Engine will die
There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine.
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty.
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart.

could be a few thing , have it put on a real time scanner, not a code reader, blue streak makes a good one, have someone monitor the engine activators and sensors, also hook up a furl pressure guage to monitor
