Reduced Power and Check Engine Light

Sorry it took so long. Cleared the codes and it finally gave me the reduced power and these are the codes P1125, P1295, @P1515. I know the P1515 is the reduced power. I looked up the other ones and I'm wondering if it is again the throttle position sensor. Again any help is appreciated. Thanks

Is it the one on the gas pedal or the one on the engine

Replaced the TPS by the peddle and so far it is working. My next question is what should the idle be. After its warm it is running around 775rpm. That is controlled through that sensor I just installed. You can adjust the peddle sensor. I think it should be around 6oorpm at warm idle.

Reduced power light came on and vehicle would not go more than thirty mph and laboring at that. Replaced MAF, Throttle body and accelerator pedal sensor. Maf new TB and APS were used parts. Everything worked fine forabout fifteen miles then same problems manifest. Help Cecil, Help, at my wits end (short journey lol). God Bless Chas

Okay then thanks to all of technicians out there that assisted me. I will look at the site and see if in the future I can help out also.

Thanks for replies. Limped into shop they hooked up their Hi-tech "$20,000" machine now they tell me passenger side catalytic converter is shot and needs replacing? Thoughts? I was going to put in a universal since both sensors are in pipe above and below catalytic converter. Thoughts?

HMAC300 please advise on my 2001 reduced power post thanx God Bless Chas

The reduce power light came on while driving in Kissimmee, Florida. Temperature here is not cold, and now the truck wont start. It has done this in the past but goes away and does not come back for a few moths. Having to pay a tow truck almost $200 to bring back home, because the truck will not start up this time. As if the battery was dead or something.
In the past when it has done this, the truck would not turn off completely, but when trying to hit the gas, no matter how much, it would not go faster than 5-10 miles. Tried to crank, but would not do anything. How can I fix the issue? Please help!

To the left of the A/T Oil Temp light it has the Reduced Speed light, it is on. The car will turn on and then turn off again. After that it won't turn back on. I have to wait at least an hour or two to try and turn on again. I am not able to take to scan, but will take all the help I can to fix myself.
