SOURCE: why does reduce engine power light comes on chevy

That is a hard problem to pin point without knowing what codes the computer has stored. It can be any number or sensors or engine problems.

You can go to most auto parts stores and they will pull the codes for you for free.

SOURCE: code p0121 TPS

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!

You need to get the computer scanned. This can be done at Auto Zone or similar parts stores free of charge. More than likely you will just need new spark plugs and/or plug wires but I cannot be certain without the engine code.
Hope this helps, remember to rate this answer.

06 chevy silverado 1500 LTZ 5.3lt code U0107 Dashboard show "engine power reduced " scan recommend replace Electronic Throttle Body Module. mechanic told me throttle body. This is completely different


I have worked on these and have found that there are issues with the throttle "body". You should be able to get one on ebay for around $80. They have wiring issues inside and get poor connections after warming up and cooling down repeatedly. Hope this helps.

Chevy 2005 4x4 silverado low oil pressure replaced oil sending unit and the cluster 137000miles no noise from engine


By the time you hear noise from the engine it will be too late for that engine. You may need an oil pump replacement. Have a mechanic check the oil pressure. It's cheaper than replacing the engine.
