2002 ... I've been getting a soft engine fault all three lights on and reduced power. This usually occurs if I accelerate hard but also happens if I take a small pot hole in the front, a little bump seems to trigger it as well. Also engine resets to normal after removing key.
It's not logging the fault as had dealer read ECU and said was not logged.
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 RepliesThis has happened to me twice now, 2 weeks between occurrences:
Driving to work, about 10 minutes into the trip - traction control light comes on, "Reduced engine power" message appears on DIC, and check engine light comes on.
The car is an '08 Prix, no charger, with 51K on it. This is actually the first trouble I've had with the car since it left the dealer lot.
I pull over, turn car off. Turn back on - traction light goes out, and engine is running at full power. The check engine light remains on for about 5 starts/stops then goes away.
I haven't had the engine scanned yet. The only thread here I could find recommended replacing the throttle body. The person decided to clean the throttle body, and that was the last post.
I was thinking of removing the individual electronic components from the TB and cleaning them and the area around them in the TB. (I have the sensor-safe cleaner for TB's).
I don't think this error condition would be a warranty issue, but I'm not sure. It's a MAJOR hassle for me to get the car to the dealer.
When I take off from a start it will intermittently stumble or hesitate, seems to be around 1500 rpm. have also noted it at higher speed while cruising. its more like a momentary power cut than a miss fire.
So far I have done the following
new fuel filters
clean MAF
new PCV valve
new spark plugs
check all hoses and plugs etc
injector clean
checked techstream for codes. there is one for a heated O2 sensor but dont think thats it.
2002. SC430
Picked up my rx300 on Monday. Got engine and vsc lights on. Tried battery off to reset. Worked for a day then back. Got a code reader and reset. Found a p00016 code? Crankshaft potion/camshaft position bank 1 sensor A correlation ?
View 1 RepliesWhere the license plate lights get thir power from? I have a 2002 SC430 and the plug is just dangling. It goes behind the plate and then if I look under the car, it is just there by the bumper and I cannot find a connector that it can reach.
View 3 RepliesI have done hours of searching about the rough idle on the SC430. What I haven't been able to find is any information about an intermittent rough idle. I have cleaned my MAF sensor twice.
I am having my mechanic replace the radiator tomorrow because of a leak and he is also replacing the idler pulley and the belt tensioner (one of them is making a noise and I purchased an extended warranty!) At the same time he will be doing a throttle body cleaning. I had my timing belt replaced as well as the water pump and had my mechanic check all the spark plugs and all were fine.
I am going to have him check the motor mounts as well. The RPM's are fine with the AC on or off and I have used Lucas fuel treatment on this current tank of gas without any results and my next tank I will try Seafoam as suggested by my mechanic.
About every 10 to 20 minutes while driving I hear 5 or six intermittent beeps. No warning lights or anything, just the beeps. What is it? I have a 2002 SC430.
View 7 RepliesOne channel (FM 90.3) delivers perfect sound for two seconds, then complete silence for a half sec. then two more seconds of perfect reception. No fade, no static, just on and off regular as a clock. This station broadcasts on two other frequencies which are behaving and 90.3 comes in fine on my other vehicle.
View 2 RepliesLexus has diagnosed a ground fault with an intermittent connection.... I am not sure how to proceed ... Could it be a light bulb connection... or does it even have these? Can the part be serviced in place... or must I replace the whole assembly?
View 4 RepliesI have a 2007 chevrolet uplander. Yesterday it started giving a message of reduced engine power and the engine light comes on.
View 6 RepliesI 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.
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.
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.
View 14 RepliesThe 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
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...
View 7 RepliesReduced 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.....
View 14 RepliesI 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 RepliesSo 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.
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...
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.
