Chevrolet - 1500 :: 2003 - Reduced Engine Power Light Along With P1516 Fault Code
I have a 2003 Chevy 1500HD 6.0L 4x4. I've recently started getting the "Reduced Engine Power" light along with the P1516 Fault code. I've checked all the wires going to the TAC Module, TPS, and MAP, all appear to be in good condition. The Throttle Body is clean and the "flapper moves freely with no sticking. I only have this issue when it is warm outside. Recently we've had fairly code days between 32-50 degree weather but on the few days that it has gotten warmer, I've had the issue. Since it seems to only happen when its warm, I believe it to be a moisture issue, but I'm not sure.
View 6 RepliesChevrolet - Tahoe :: 2003 - Reduced Engine Power Error
From time to time, my Tahoe gives me the "Reduced Engine Power" error, and I lose acceleration capabilities and have to pull over. After a min or 2, I can go again, but the check engine light stays on. With no rhyme or reason, the light will be on or off on the next start up. The problem may or may not happen during a short ride or may happen quite often. I have replaced the Accelerator Pedal sensor, so that is not the problem, I'm assuming.
I've been told that it is the Throttle Body that needs to be replaced, but no mechanic can confirm. They just want to replace it and the pedal. I would really like to keep this truck for a couple more years. Other than this problem, the Tahoe has been pretty good to me. Here are the codes that have been read: P1125, 1516, 2120, 2125 ....
Chevrolet - Malibu :: 2010 - Engine Reduced Power / Disabled
I have a 2010 Chevy malibu LT with 120000 miles. And today while I was driving my engine disabled and there was a message of reduced engine power. After letting it sit I turned the key and nothing happens all the lights and things come on but the reduced engine power and engine disabled shows up. The car won't crank up. Earlier that day I had my engine coolant temperature sensor replaced. What is going on or what needs to be done? I am getting so frustrated with this car.

This has been a decent truck... lately you drive for 5 miles or so.. it goes to reduced engine power. if you get to side of the road and turn completely off and sit maybe 10 seconds or so, it goes fine again.... I have tried to get a computer reading, but by the time I have gotten it anywhere, the check engine light is off again..
View 5 RepliesChevrolet - Tahoe :: 2003 - Reduced Engine Power Message / Speed Losing
I have a 2003 Tahoe that I love but is driving me crazy with a "Reduced Engine Power" message. I am driving along and suddenly it dings at me, the message center says "reduced engine power" and I am losing speed. It goes into a "limp mode" in which I cannot accelerate, it cannot pull itself up a hill, and the engine misses badly. I can pull over, shut it off for a couple of minutes and then start it up and run again just fine until it decides to do it again.
There seems to be no rhyme or reason, one day it did it 4 times w/n the first 20 miles, then ran 100 miles w/o doing it at all. I recently took it on a trip that normally takes me 1 1/2 hours, it took 2 1/4 hrs that day because I had to pull over so many times. I was having to stop every 3-4 miles by the time I got there. My usual mechanic has completely given up, told me to trade it. I have had it to another mechanic for over a month now, 3 times he has thought it was fixed, but it wasn't. One time, I didn't even make it the 5 miles to my house before it acted up again.
One other note on this: this past trip I made, I left early in the morning and my lights were flickering high/low. . . this went on for several miles. Finally my lights quit flickering, then I lost engine power, pulled over, shut it off. When I started it back up, the lights started flickering again. The cycle seemed to continue, once the lights would settle, the engine would lose power. I took it to a parts store and had the battery and alternator checked. They said both were fine. (Had never noticed the light thing before, but I can't think of a recent trip after dark.) How I can pass along to my mechanic?
Ford 6.7L Power Stroke Diesel :: Check Engine Light Came On / Reduced Power Then Died
I started my '16 6.7 this am and drove it about a mile.
The check engine light came on and at the same time the display said "Reduced Power". I decide to turn around and try to make it back to my shop but shortly after turning around the display said "Low Fuel Pressure" and within a couple of hundred yards it shut down leaving me stranded by the side of the road.....
I called my local dealer who gave me the Ford Cares 800 number. I got a flat bed in about 1.5 hours which I didn't think was too bad considering I live in the country and they brought it to the dealer. The SA said it might be a couple of days before they could look at it as they were pretty busy... What it could be? The engine is stock with 9100 miles on it...
Saturn - Vue :: On Random Startups Power Reduced And Check Engine Light On
I have been battling a random reduced power issue with my 2004 Vue, 85000 miles, 4 cyl engine with manual transmission. On random start ups I will get the reduced power and check engine lights. No codes are logged but the freeze data will read mostly 2176 and occasionally a 2101. I have replaced the throttle body and pedal assembly plus checked and reseated the ecm connections. The problem still shows up randomly at start-ups. If it does appear, it seems that if I shut the engine off, turn the key to on without the engine running for about a minute, then restart the car, the car will start ok. It's almost as if the ecm has to relearn the throttle or pedal positions when this occurs.
View 4 RepliesVolvo :: Reduced Engine Performance Error Message On 2007 S60
While my wife was re-parking my 2007 S60 this morning (currently at 73,143 miles), the error message "Reduced engine performance" came up.
She had switched-off the engine before calling me on the phone to report it, else i would have told her to rev the engine to see how far the rpm gauge could go.
While checking through the error on google, noticed there were several complaints on this in the past but could not see any inferences on what was done to resolve this except for guys who mentioned repeated visit to dealership.
When she switched-on the engine again, the error message didn't come up and she could rev the engine up to 6500rpm, i intend using the car for a long journey next week and do not want any breakdowns.
Ford 6.7L Power Stroke Diesel :: Reduced Engine Power Warning Message Pop Up
I have seen this pop up on the truck I think 3 times now over the first 4000 miles on the truck.
Usually it's when I'm on the highway around 70mph or so.
It comes on for a few seconds, then goes away. I do have an exhaust / tune on the car.
Ford 6.7L Power Stroke Diesel :: 2016 F350 - Reduced Engine Power
2016 F350 6.7; ccsrw, 22K on truck (zero issues previously). Stock other than titan fuel tank that was installed at 100 miles.
700 miles into todays trip, pulling trailer, snowing, in 4x4, tow/haul; pulled out to pass, got into it for a bit and got "reduced engine power" error, truck slowed, would not show boost on gauge, wouldn't rev over ~1900. CEL is on.
Pulled over, stopped, checked under/over and didn't find anything. Shut off truck, started back up, CEL is still on, but truck runs OK. Ran for another 20 miles or so and was OK for how I drove it (including boost showing on gauge). Not hot rodding, crappy road conditions (snow). Got on a big hill from dead start and got into it a bit, about 3K same error came on and she went back into limp mode. Same deal, stopped, shut off, back on, was able to keep going. Was only couple miles from motel at that point, so she is on break right now.
Of course I'm 400 miles from home and nowhere near a dealer. I have a code scanner, but nothing with me to pair it with (daughter has tablet with her, ha ha).
Should I keep going or find a dealer/tow/other? If she will keep running "normally" below 3K, then I can make it home as I don't need to horse it that bad on the roads I'll be on.
Truck has had fuel filters replaced on schedule, dealer has done all service work (oil, etc). Fuel filters were done 7500 miles ago.
This trip, was on third tank of fuel. Had just put in 30 gallons at last (big) truck stop about 15 miles before this issue happened, have 50 miles on this tank. That was 30 gallons into 50 gallon tank.
Ford 6.7L Power Stroke Diesel :: Running Rough / Reduced Engine Power
I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

The truck (2012 f350 6.7 lb cc 131,600 miles) started fine. Then while i was setting up the defrost i accidentally hit the ac button. Well I then hit it again to turn off. At that point the engine stalled. Which has never happened to me before. I started it back up which took a bit longer to get it to fire. It now says "Reduced engine power" and runs kinda rough. I thought well im at the end of my fuel filters life so why not change it since i had one. Well the. The FF housing broke. After replacement FF housing and filter it will no longer start. I took the filter back off and checked to see if it was cross threaded or sucking air. I checked that twice. Still no start cranks fast and strong. Codes are
P2138 something to do with the gas pedal
P0193 fuel rail sensor A high
P06A6 voltage on circuit A is whacky (paraphrasing here)
P0532 ac pressure sensor low
Ford 6.7L Power Stroke Diesel :: Reduced Engine Power Warning
Getting reduced engine power warning with no other lights on the dash and what is probably causing it. The truck is a 14 f450 cab and chassis model. I had just had it to the dealer for this problem and the check engine light was on and the said there were two sensors going bad on the exhaust so they changed them out and sent me on my way. Well after driving the truck around all day and not one issue it had just decided to set the rep warning again but did not set off any lights...

Reduced Engine Power warning and fuel leak? While towing our 37 Fiver uphill a couple of days ago, the warning popped up along with the CEL. Indeed, the truck did lose a tremendous amount of power. When I found a safe place to stop, the diesel smell was terrible. Further inspection revealed that fuel was dripping down the side of the engine from somewhere above the oil filter. I limped along another 15 miles to the campground and unloaded the 5<SUP>th</SUP> wheel and brought the truck in to the dealer this morning. They aren't giving many details of their findings thus far. They say that they've talked to Ford engineers and that they'll have to put a dye into the fuel to detect the origin of the leak. They suspect the high pressure fuel pump, but by the time they remove enough "stuff" to get to the pump, they can't run the engine to witness the leak. This is my first Ford in 30 years behind the wheel and my first diesel. After 8k miles on the truck.....

I haven't had any issues with this truck before but last night I pulled out onto the highway and my check engine light came on and a message saying engine power reduced I finally got it to reset after 4 times of shutting the truck off, was wondering what this may be without knowing the code. I tried plugging my edge cts into it from my 6.0 but it wouldn't communicate guess it needs a update trucks a 15 f350 with only 30000km.....
View 2 RepliesFord 6.7L Power Stroke Diesel :: Reduced Engine Power Message - Code P164A
So I just went on a vacation pulling my horse trailer (first time leaving the state with this truck) and at about 5 hrs into the trip I had a message Reduced Engine Power and went from 70 on the interstate to 10 miles an hour and slowing rather quickly. I ended up shutting it off and restarting and it came back just like normal. I found the nearest ford dealer and they put the computer on it and it showed absolutely nothing, no codes and nothing wrong. The mechanic reset some things and we went on our way.
Then I ended up getting a check engine light saturday. I found someone to read the code and it came up with P164A which is an O2 sensor, he was able to clear it and I put on probably 50 miles today and no check engine light. I have about a 10 hour drive back home. Still debating if I take it to ford near here if they will do anything now that it doesn't show a light?? I hate to chance getting broke down on the highway with a truck that will basically shut down like that?? It just doesn't make sense to me.
Ford 6.7L Power Stroke Diesel :: CEL / Low Fuel Pressure Along With Reduced Engine Power Warning
I just had my first fuel filter change (about 9,000 miles). After the shop changed both fuel filters with factory Ford ones, a check engine light came on and a "low fuel pressure" warning, along with a "reduced engine power" warning. It also stalls a lot and takes a long time to restart.
Obviously, they didn't do it right. I suppose there is air in the lines or something didn't go back together correctly.
My '06 seemed to purge itself, but this truck obviously won't. It is not even driveable to get it back to the station, to see if they can correct the problem.
The thing is, I watched them do it, so if someone can ask me the right questions as far as what I saw, maybe I can lick the issue in the driveway myself.

View 11 RepliesFord 6.7L Power Stroke Diesel :: 2011 F250 Won't Start After Getting Reduced Engine Power Message
I have a 2011 Ford F250 6.7 Powerstroke. It has 107,000 miles on it.
The other day I was driving it down the highway and it got a Reduced Engine Power message on the dash. It lost power and I got off the highway to the service road. Then it died on me.
Had to get it pushed to a station then towed home. It wouldn't start. The starter cranks over for a few seconds but engine won't start. Checked all the fluid levels and batteries. My DEF fluid was only a half gallon low.
What I have noticed is that the DEF level indicator hasn't reminded me that it was low for over 4-5 months now. I had been putting in about 2-3 gallons every 3 months or so. But it hasn't reminded me lately and I just forgot. This is my first diesel.
