07 chevy equinox , it goes into power loss mode, check engine light on and stabila track on , i was told it was the tps sensor is that the sensor on the gas pedal or is that in the throttle body

SOURCE: Tps Sensor low input p-0227

P0227 also indicates the throttle PEDAL position switch control Circuit.Not only the throttle position sensor at the engine.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

Got to be a reason for the price difference if it's quoted from the same place.

THERE IS A TP SENSOR BUILT INTO THE THROTTLE ACTUATOR. THESE TRUCKS HAVE BEEN KNOWN FOR A FEW PROBLEMS IN THIS AREA. THROTTLE ACTUATOR IS NOT SERVICEABLE. THE THROTTLE BODY WILL NEED TO BE REPLACED IF IT IS PROVEN FAULTY. THE APP SENSORS ARE LOCATED IN THE GAS PEDAL MODULE. THESE SEND SIGNAL TO COMPUTER TO TELL IT WHERE YOUR FOOT IS, THEN COMPUTER SENDS COMMAND TO THROTTLE ACTUATOR TO OPEN OR CLOSE THROTTLE BASED ON THIS INPUT. THE SENSOR IN THE THROTTLE ACTUATOR DELIVERS A MESSAGE BACK TO THE COMPUTER TO TELL IT WHAT THE ACTUAL THROTTLE POSITION IS. IF THESE SIGNALS DONT MATCH(WHERE THROTTLE IS COMMANDED AND WHERE IT ACTUALLY IS)THE CHECK ENGINE LIGHT WILL ILLUMINATE AND THE VEHICLE COULD GO INTO A REDUCED POWER MODE. HOPE THIS HELPS YOU!
