2000 Ford Excursion - V10 02 Monitors: NEW INFO
2000 Ford Excursion - V10 02 Monitors: NEW INFO
This one is weird to me. Vehicle has no downstream 02 sensor???? The upstream 02's are switching between .15V and .88V and both are going rich to lean normally. The pcm shows the evap, egr, catalyst and secondary air systems "NOT AVAILABLE"?????? The 02 & 02 heater readiness tests will not reset and vehicle has been driven constantly for eleven days. NO CODES HAVE SET. I am confused. Why no downstream 02?, Why evap?, cat?,egr & SAS are not available? Keep alive pin has battery voltage. I'm thinking PCM but not positive??? Has anyone seen this before?

Re: 2000 Excursion V10, 02 minitors won' reset
When you say the vehicle has no downstream o2, do you mean that nothing shows on your scanner or there physically is no sensor? It should have 2 upstream and one downstream. This vehicle does have an Evap system. What scanner are you using? Does it auto-id? Maybe try one year newer or older and see if you have the correct data.joetngallagher wrote:This one is weird to me. Vehicle has no downstream 02 sensor????

Absolutely. It may be the scanner.
As far as setting the monitors, did you try the drive cycle?

Re: 2000 Excursion V10, 02 minitors won' reset
I used 2 different scanners, Genesis and Modis. I only saw upstream sensors showing up on both, in global & vehicle specific. I looked at vehicle and there is no downstream sensor, not even a place to put one, in the exaust and the customer claims he bought it new and has never had any exaust work done. vehicle has 105,000 miles. Cat and Converter are both factory.
Due to my stupidity I never looked to see if vehicle had evap and egr system. There is no evap or egr system.....DUH I just assumed(and we all know what that does) these systems were mandatory on all cars made in USA.
Put vehicle in drive cycle and ran it 5 days then put it in drive cycle again and ran it 6 days. Approximately 75 miles each time with several restarts and cool downs.

Check the door tags....could be a gray market car. This vehicle should have an evap, egr and post cat.joetngallagher wrote:I used 2 different scanners, Genesis and Modis.

Also, post the data on the certification label. If it's an american vehicle, it'll say there. Should be a nuber like 9 EQM-BAA or a larger number like 0 AJ1 AA 6 A 00. There was a protocol changeover in 2000.

Re: 2000 Ford Excursion - V10 02 Monitors: FIXED
Probably a Grey Market car. Vehicle info sticker isnt there. This vehicle did not have a downstream O2, wiring for O2, or a place to put one. Took it to emission testing center and explained problem. They tested it at the tail pipe and it passed. I realize that this is not a FIX, but at least I now know that testing center is aware of the problem and they worked with me. Also, this is the first time I ever got some assistance from any testing center, they usually just fail vehicle.

Re: 2000 Ford Excursion - V10 02 Monitors: FIXED
Soooooo, if this is a gray market car, how did a dealer sell it to an American customer? Something doesn't sound right. Maybe not all the facts here. What's the VIN?joetngallagher wrote:Probably a Grey Market car. Vehicle info sticker isnt there. This vehicle did not have a downstream O2, wiring for O2, or a place to put one.

Re: 2000 Ford Excursion - V10 02 Monitors: NEW INFO
i've had a few that were purchased in mexico. years ago a customer brought a 82 suburban into the shop for a tune up a few years back and when i opened the hood i felt like i was in a time machine. if your ever on vacation in mexico or the carribean look around at all the cars. 5 years ago a person that worked at the hotel we were at heard me talking about nascar and he was a huge fan also. he took me out to see the new car he had just purchased and decked out. i went along and he indeed had. he had contigency stickers on the fenders etc. it was a riot. a toyota tercell. he popped the hood and i crossed my arms into a crusifix. it had points and a venturie carb. i hid in my room the rest of the day..................................... you see cars and trucks you've never heard of.
never argue with a fool, they'll drag you down to their level and beat you with experience
