Reduced power light is on and truck will not pick up speed

The reduced power light goes off and on at times. When it comes on the truck has a slow take off and will not pick up speed over 40 mph. I bought the truck 2 months ago as is and the light came on the first day but when I stopped and turned the ignition off it didn't come back on. Now its on again and turning off the ignition isn't working this time.

Hello,

I just purchased my 2001 Rodeo the engine light came on. I replaced the spark plugs and oxygen sensor and though the car seemed to ride a little better, the engine light continued to stay on. After a week or so I experienced the exact same problem. The vehicle would not go over 40 miles per hour and the reduced power light came on. I had it put on a machine and got many different codes, however, all the codes lead up to the computer. I had just the computer replaced and all is well. Most of the time, the read out will show many codes, but most of the time they all lead to just one part. Try that. It worked for me and now it runs great.

This happened to my 2002 EXT and two of my buddies Escalades. All 3 were AWD. All we did was replace the Front Hubs. I replaced both Front hubs and the speed sensors. Actually I replaced the speed sensors first because thats what code was coming up, and it didn't fix the problem. So after talking with a freind who is a big time GM Mechanic, he told me it's probably my barrings and since they are sealed I needed to replace the hubs. This is an easy job. I did them myself, and I am by no means a "mechanic".

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

Reduced engine power on a 2003 chevy taho light came on and it pulls slow what to do


Reduced power is a mode the engine goes into when there is something wrong with the cooling or the firing. If the engine gets to hot it uses the pistons to air cool. This of course is not a for sure but where I would start.

No, you need to have it scanned at the local autoparts store (for free) or to your dealer for repairs.

Said reduce speed and move real slow


That has happened to me before. I parked the truck, turned off the engine, waited for about 5-10 and restarted. As long as the reduced speed indicator and/or the check engine light don't remain on you are good to go...hope this helps

Reduced power light is on and drives slow


Try adding gas line antifreeze to your fuel. If you have water in the gas, this will clear it up. Water in the gas line can turn to slush or even ice when the temperature dips below freezing, causing reduced power because of reduced fuel flow.

Locate the IP to body harness connector, which may be located in and around the left hand kick panel area or inside the IP. Check to see if there is a water leak into the area and repair as necessary.
