Question about 2007 Chevrolet Silverado 1500 2WD
Is there a tps sensor on this model on the throttle body or is there only a throttle pedal sensor on this 1500 model? I unplugged the sensor on the gas pedal and sprayed air, reset computer by disconnect battery for a few hours. Drove truck this morning and the check engine light came back on after about 10 miles in stop and go. Thanks, Ann
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!
