Ford Excursion :: Misfiring - O2 Sensors Out?
Jan 26, 2014
So Wife did this nice "How-To" for the site and then we celebrated with a trip to Steak N' Shake. Halfway there I could feel it running a little off so I pulled up the app on the phone and connected it. I pulled up the codes and this is what I got.
So am I looking at an O2 sensor you think? It's shifting early and chugging a little as well. When driving it sounds a little like I have dual exhaust or a flowmaster. When sitting still at a light there is a small bump like bass turned WAY low coming from the exhaust as well. I turned around halfway there and went home and we took the wife's Highlander

I can't find any info about this "always on" reverse light issue. My searches show that most people with the problem only have it when they put it in to revers. Mine's broken but the light is on all of the time indicating it's not working.
I can go through the sensors, but I think the system only recognizes sensor failures when the car is in reverse. What's my first/next step?

So when I put truck in reverse my back up sensors constantly beep. Not a beep beep beep like they are supposed to. More like a annoying Beeeeeeeeeeeeeeep . Doesn't do this all of the time but most of the time.

My Excursion had a mangled rear bumper when I bought it recently. I just bought a salvage one to replace it. I had it installed today. I want to salvage the backup sensors in the old bumper along with the license plate lights. How do these come out? They seem locked in there to me.

Ok, so it seems I have 3 bad backup sensors on the 2002 Ex. Background information for those considering a repair:
I put the Ex in reverse, key in run and can hear "fast ticking" from only one sensor. Sensor removal is easy (at lease on the two outside sensors). Two tabs on the black housing in the bumper hold the cylindrical sensor in place. Release the two tabs and work the sensor out. I haven't tried to remove the bad inside sensor yet as there is a lot less room to work there.
Once removed, a single tab on the wiring harness connector holds the sensor in place.
Here is the problem I have. I can't get the sensor to LOCK back into the connector. I have backed the connector against the bumper and pushed on the sensor with all my strength and I cannot get it to lock back into the single tab on the connector.
Is there a trick I am missing? I am ready to try vice grips but I fear I will damage the connector.

I'd really like to add these to The Beast, but don't want to drill through chrome. My bumper has some plastic running along the top (see pic). Just looking for info for the same bumper mounted the sensors there with success.

2000 Excursion V10.
Recently cylinders 1,2,3,4 wend dead on my wife's Excursion. I searched here for a pin out diagram so I can check all the wires from the coils to the PCM. I changed the coils on those 4 cylinders with no change and then swapped them with the coils on the left side of the engine. the problem stays on those 4 cylinders. Any link to pin out the wire harness for the coils to the PCM

About a month ago I changed the plugs on my EX to see if I might pick up a few tenths on my mpg. There was no real issue, but I wasn't sure when they were done last. I used Autolite platinum's(AP103). Since I changed them The truck has a hard miss during acceleration. It feels like it is missing on multiple cylinders. It is most noticeable below 2000 RPMS. During hard acceleration it almost clears out, but the the truck feels like a pig.
There is also a miss at idle, but it goes away if the truck is in park, or neutral. Thinking that it may be my choice of plugs I went back last week and replaced them again with motorcrafts. Still having the same issue. Have scanned the truck with both the Torque app, and an sct scanner and its not throwing any codes. I'm at a loss. In the last year I have replaced the fuel pump, and the filter so I'm ruling those out.

So Friday before last my ex laid down on me while i was headed to work. So I parked it in a walmart parking lot and caught a ride to work with a friend then had it towed home that evening. Problem i was having is it started running really bad, miss firing, smoking, and sounding real rough, but I wasn't getting any trouble codes. So after both uvch's, icp, ipr, icp pigtail, checking fuel for water contamination and pulling my hair out, i decided to check the oil and found it to be 4 quarts low. Talk about feel like a knuckle head.... While it was down it did receive a new water pump, a diesel site 203* thermostat, new billet thermostat housing, Gooch's Radiator Flush Procedure, and some fresh rotella etc.

I have a 02 ex 118,000 on it, not a every day driver, mostly weekend and camper towing. The truck was running great, stopped at a light and the engine started hesitating, the od light was flashing, and then it died.. started right back up no od light, but was still hesitating/missing took it to a local shop, they hooked up a scanner and said that several coils were misfiring. My question, replace all coils? go with oem coils, or aftermakert?

I have a 1998 Ford Explorer 4.0 V6 with 200K miles. I plugged an OBII scanner with live data readings and my o2 sensors never relayed any information (voltage), they all ead -100% and the voltage never changed. Could all four be bad? I left the truck running for 15 minutes with the scanner attached and nothing changed.
BANK 1 SENSOR 1 = -100%
BANK 1 SENSOR 2 = -100%
BANK 2 SENOR 1 = -100%
BANK 2 SENOR 2 = - 100%

It's abnormally cold here in the Northern Va area single digits with windchills in the negatives. I ran through the car wash, one of those that hand dries it afterwards to get the salt off my truck. After running the roads I went to back in to a spot and the sensors are going off. Nothing is blocking them so I'm thinking water got inside and froze?

My question is about a 2000 ford windstar with 3.8 engine. Does this vehicle have a coolant temp sensor and sending unit or just a sensor?
