Ford F-150 - 1997-2003 :: OD Off Light On The Shift Selector Blink / Service Engine Soon Light Comes On
Aug 7, 2014
I have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.

My wife has a 2003 Pontiac Grand am GT 3.4L V6. A few days ago my wife was out and tried to start the car and the service engine light came on and began to blink. (Prior to this the car was running well with no service engine light) The car was running very rough at this point so we shut the car off and I pulled the codes at witch four codes came up witch were: P0205, p0206, p0300, p0443. So I had the car towed to the shop and they said that they thought that it was the oxygen sensor but after that had been replaced they had concluded that the oxygen sensor was not the problem so they had placed the old one back in. Then they said that they restarted the car and it was running fine but then pulled it out of the shop and began to run rough again.
At this point they were thinking that there was a short so they checked the wiring from the ecm (?) back to the oxygen sensor and could not find any problems. And needless to say they started the car and it began to run fine again so they told me to come and pick it up and drive it for the weekend just to see if it was a lose connection that was possibly there. So needless to say once I picked it up the service engine light was still on but the engine sounded good so I figured I would drive the car home and maybe the light would shut off. Well upon taking off and getting a few miles down the road the engine started to idol at 2000 rmp when in park or neutral.
So I stopped and pulled the code and got P0443 again so while I had the scan tool connected I cleared the codes to see if the light would come back on with the same code or with multiple again. The service engine light stayed off. So the high idol continued for a few miles I also did try to restart the car and the problem did persist. About 5 more miles down the road the car started to overheat and the reservoir had overheated. So at this point the engine sounds good it is not running rough but is really high idol. The check engine light did not come on since I cleared the codes in that short drive but I do not want to drive it because of the overheating. I do know that the coolant level was good when we started the car.

2001 F150, 5.4L gas, 4wd, stock, 217k miles, auto trans. Bought it used about 4 years back.
Currently away from home base. Left Saturday for a 600+ mile trip. All fluid levels are good. Truck has been reliable. No major issues other than an alarm malfunction a while back which got sorted.
About 90 miles into the trip down the highway, the service engine light comes on. Hmm. At the next fuel stop I tanked up. Started and it was a bit rough the first few seconds and then settled. Seemed to have an engine noise I had not heard before.
Pulled over in the station and popped the hood. Oil good. Coolant fine. Power steering fine. Listening to it I could definitely hear an unusual sort of "ghost" like sound. Hard to describe. Sort of like a low "woooooo." It was low, but definitely there and not normal. Could be unrelated to the engine light. Pulling out of the station the sound varied and got louder with slight acceleration. Possibly beginning of an accessory bearing meltdown?
No acceleration or dying issues. Got back on the highway and kept on trucking for 600+ miles. No running issues. No shifting issues. Ghost noise not noticed at highway speeds.
The power steering pump is probably in need of replacement at this point with this mileage. It does drip slightly, but not a lot. It may be the original pump for all I know. Same with the water pump.
The alternator was replaced last year with a Bosch unit. I have never replaced the O2 sensors. Stock exhaust. Spark plugs were replaced a while back with Motorcraft platinums.
It is now Sunday night and I went out to listen for the sound, and it is not there anymore, but the service engine light is still on. First things to check with a truck that has 217k miles on it?
Was tempted to bring it to the dealer here, but it seems to be running ok in spite of the light coming on. So I may leave it until I get back home and check it more myself then. Can't do much here since I don't have my tools/service manuals etc with me.

The Service Engine Soon light has come on on my 2000 F-150 with a 4.6L when I was driving home in the rain. It has about 120,000 miles on it now. What are some of the main reasons why this comes on? Oxygen Sensors?

2001 F150 5.4 Auto ... Truck was running excellent. Engine light and overdrive light begins to blink and it acts like its running out of fuel or water in gas. Baring made it home. Cleared the code and it comes back. Transmission seems fine.

Driving while in 4x4 HI up a hill the truck started to slip. I stopped, shifted to neutral, and engaged 4x4 Low. I shifted back to drive and started moving up the hill. The engine started to lose power and the "Service Engine Soon" light began to blink. I put the truck in park. As I let it run a little bit, the engine started to shake as if something was very imbalanced. I went to check under the hood, and confirmed that it was shaking quite noticeably. There was no grinding or clattering of any kind though.
I turned the truck off for a bit, and then restarted. There was no light or shaking upon starting up; but as soon as I put it in gear and started driving I could tell it was losing power, the light came back on, and the shaking ensued. This occurred in 2wd, and both 4wd lo and hi. I parked it at a neighbors place and there it sits for now.
I plan to try and get the codes read. My other vehicles can't make it through the snow we have right now, but it is suppose to get warm later today and might melt enough for me to get one out. I also live out in the country, so the nearest auto parts place is about 20 miles. Same with a dealership service shop. I'm hoping I can buy and return a code reader from an auto parts store to assess if this is something I can diagnose myself or not.
It is the 6.0l gas engine with the 4sp automatic transmission. The truck also has about 107,000 miles.

The Service Engine Soon light is on in my 2001 F-150. I checked the code and got PO156 generic O2; circuit (bank 2, sensor 2). What are the most common things I should look at? The truck appears to be running fine, no driveability issues.

2001 F150 5.4L Triton Motor. Everything seemed o.k. then got the Engine Service Light. Checked with reader and above codes only appeared. Read numerous articles/videos and pulled the PCV hose/boot assembly and replaced the whole thing with oem part. Visually checked for disconnected tubing = none found. After this and with the new hose assembly in place I performed a reset. With the scanner still connected restarted engine and read values: ST FTRM1&2 = -.08~+2.3, both oxygen sensor voltages are varying and the LT FTRM1&2 hang around +26 and +28.
From what I understand the ST seems o.k. but the long term is WAY OUT OF WHACK. Started it up again and took carb cleaner spray and covered all the connections I could see = no change in engine rpm. No cracks in the air cleaner body. Big plug to the MAF was inserted and plugging the hole. I am thinking of making a smoke "machine" and trying that or removing the hoses from the throttle body and plugging the holes in the throttle body and see if that clears them up. IF it does then connect one by one and keep checking the values. Lot more work but I am at a loss.

Last week my service engine light came on. Friend checked it with his code reader. Got a P0402 code insufficient flow EGR valve. I have read several different threads on this subject on another Ford truck forum, slightly confusing me. Should I trust the code and just replace the EGR valve or do a number of other things that
1. Clean the throttle body first?
2. Test the EGR valve by blanking it off?
3. Test the DPFE valve?
4. Replace the DPFE valve instead of the ERG valve since the EGR valve rarely goes bad?
5. Only get OEM parts since after market parts do not last?

I have a little more detail on when the truck starts and does not . I have gone out the past two days and put the key in the ignition and turn it to the on position and all the lights come on except Service Engine Soon light and truck will not start. I bought a ceramic electric heater and placed it on the floor directing the heat under the dash. after ten to fifteen minutes I go out and put the key in the ignition turn the key to the on position and the service engine soon light is on and the truck starts right up. I let it warm up for about a half hour and then shut it off. I then try to start it right back up and the service engine soon light comes on momentarily then goes off and the truck does not start?

My trucks symptoms include a illuminated service engine soon light, sometimes a high rpm idle, and sometimes a rough erratic idle. When a scan was done it indicated the oxygen sensor was defective. The issue is: which specific one (there are multiple oxygen sensors) or how could I check or determine the faulty one for sure. I am trying to economize and replace only the bad one myself if possible. I own a good multimeter, can it determine the bad one? 1999 F-150 4.2 Litre V6 oxygen sensor dillemna....

I have a 1998 f 150 v8 4.6 ltr xlt. A mechanic told me that if my tranny gets hot the OVERDRIVE LIGHT will start to blink. It sounds strange to me, should I have a guage installed? I will be towing a trailer this summer.

Put foot on brake, selector in P it will start but will not shift.
Put foot on brake, turn key on, put selector in N it will start and shift R or D as normal EXCEPT do not shift to P as it will lock up and you have to start all over again.
Selector is basically aligned on the letters appropriately.

So i replaced the faulty injector and the truck starts up great and runs great. The only issue is that now when i accelerate, the SES light comes on until i let it up a little. If i am at cruising speed or just a steady speed the light goes off. I havent checked for codes yet because the light didnt stay on. I have AE and know how to use most of it. Is there something i should be looking at? Could it have something to do with the Blue/Gray CPS i installed or maybe there could still be an air bubble in the oil rail from when i drained the rail ? I have a DP tuner and stage-1 injectors. Regardless it sure is nice to have my truck back out on the road. It was a horrible 3 weeks without it.
