First off , I'm new to the forum and like to say hello to all the Ex owners out there. My problem is as follows. I bought my Excursion from auction and it was just sitting at an impound yard for close a few years. It needed a battery replacement along with fluids and a tune up. After work was completed the truck ran great and still does. However, when I took it to get Smogged (California) the tech told me that the heated o2 sensor and o2 sensor monitors are not ready. The tech suggested driving the vehicle a minimum of 100 highway miles before bringing it back. After a trip to Las Vegas and back with the excursion, I took the truck back in to the smog tech to finish the smog. No luck, the monitors were still not ready. He suggested to keep driving it for another week and bring it back in. Well a few weeks and another 600 miles have past and the monitors don't want to set.
I have searched the forums and found some information but not very specific solutions , if any. My truck is the V10 4x4 with 200k+ miles. Any info would be appreciated.

 

Grab your digital camera, open the hood, then take a legible photo of the stickers on the underside of the hood near the latch, assuming the hood is original and the stickers can still be read.

Post those photos.

Also, edit your thread title to include "California" and "smog test". That will get the attention of the right folks (ones who have deal with that silly state).

 

Thanks for your response , I will locate and take pic of the labels in the morning. Just curious about what info the labels might have that are relevant to o2 monitors.

 

The labels will tell what emissions standard your vehicle was manufactured with which will have a direct bearing on the emissions testing.

 

what year? I can give you the drive cycle for the monitor if it falls between 96 and 01

 

Start the engine and drive the vehicle for 7 minutes.
Drive in stop-and-go traffic for 6 minutes, include one idle.
Accelerate to 72 km/h (45 mph) [56 km/h (35 mph) on Escort/Tracer at more than 1/2 throttle]. Maintain speed for 1 minute
This is drive cycle for 99 v-10 truck for HO2 Sensor

 

Don't waste time screwing around with trying to do "drive cycles" until we know that emissions system is in your truck. If you have a 49-state calibration, you can drive the truck till the cows come home and those monitors will never "complete".

 

Thanks for the replies Gents, as it turns out there is no label near the latch. Seems as though it has had the hood replaced or work done on it. I have attempted the "drive cycle" with no luck , because its near impossible to do without the truck being on a dyno. I'm going to order some o2 sensors for the front and replace them. On a side note, the shift cable was melted because it was resting on the front O2 sensor... Good times!

 

FYI: Either set up your signature to say what year make and model of truck you have or always when you post a question list that information. It really helps. Hope replacing them helps. Although they should through a code if they are bad.

 

See post #7.

Check for downstream (post-cat) O2 sensors. If none, it's a 49-stater and your testing station needs to do things differently.

 

Ok Gents , my truck is a 2000 V10 Excursion . A quick update, took your advice and checked under the truck for a downstream O2 sensor, what do you know, there ISN'T one. every mechanic I spoke with all said there are 4, some said 3 and they all needed to be replaced. I finally did a local check and was told to go to a smog tech who knows his ****. He said that my model only had 2 upstream sensors but they weren't ready yet (monitors) I was told to either change the upstream sensors (they might be lazy) or keep on trucking Intill the monitors are ready. He also said it could take up to 1000 miles. FML

 

This is drive cycle per Ford Shop Manual for your vehicle. If you are not using a code reader than it is important to note temp outside and that truck is warmed up to normal operating temp. Then do the drive cycle for HEGO. That is the one you're concerned with. I have blocked the wheels on my truck and jacked it up and put the rear on stands to do these tests. It is tiring and crummy but it does work. Yes the dealer can use a dyno but usually a tech will do the drive cycle on a back road or in city streets. Evap is the longest one to check in. I hope this is helpful. Just in case you don't know, IAT is incoming air temp/outside temp. ECT is engine coolant temp.


OBDII Monitor Exercised Drive Cycle Procedure Purpose of Drive Cycle Procedure
Drive Cycle Preparation 1. Install scan tool. Turn key on with the engine off. Cycle key off, then on. Select appropriate Vehicle & Engine qualifier. Clear all DTC's/Perform a PCM reset. Bypass engine soak timer. Resets OBDII Monitor status.
2. Begin to monitor the following PIDs: ECT, EVAPDC, FLI (if available) and TP MODE. Start vehicle WITHOUT returning to Key Off.
3. Idle vehicle for 15 seconds. Drive at 64 Km/h (40 MPH) until ECT is at least 76.7°C (170°F).
Prep for Monitor Entry 4. Is IAT within 4.4 to 37.8°C (40 to 100°F)? If not, complete the following steps, but note that step 14 will be required to "bypass" the EVAP monitor and clear the P1000. Engine warm-up and provide IAT input to the PCM.
HEGO 5. Cruise at 64 Km/h (40 MPH) for at least 5 minutes. Executes the HEGO monitor.
EVAP 6. Cruise at 72 to 104 Km/h (45 to 65 MPH) for 10 minutes (avoid sharp turns and hills). NOTE: To initiate the monitor TP MODE should = PT, EVAPDC must be > 75%, and FLI must be between 15 and 85%. Executes the EVAP monitor (If IAT is within 4.4 to 37.8°C (40 to 100°F).
Catalyst 7. Drive in stop-and-go traffic conditions. Include five different constant cruise speeds, ranging from 40 to 72 Km/h (25 to 45 MPH) over a 10 minute period. Executes the Catalyst Monitor.
EGR 8. From a stop, accelerate to 72 Km/h (45 MPH) at 1/2 to 3/4 throttle. Repeat 3 times. Executes the EGR Monitor.
SEC AIR/CCM (Engine) 9. Bring the vehicle to a stop. Idle with transmission in drive (neutral for M/T) for 2 minutes. Executes the ISC portion of the CCM.
CCM (Trans) 10. For M/T, accelerate from 0 to 80 Km/h (0 to 50 MPH), continue to step 11. For A/T, from a stop and in overdrive, moderately accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop vehicle and repeat without overdrive to 64 Km/h (40 MPH) cruising for at least 30 seconds. While at 64 Km/h (40 MPH), activate overdrive and accelerate to 80 Km/h (50 MPH) and cruise for at least 15 seconds. Stop for at least 20 seconds and repeat step 10 five times. Executes the transmission portion of the CCM.
Misfire & Fuel Monitors 11. From a stop, accelerate to 104 Km/h (65 MPH). Decelerate at closed throttle until 64 Km/h (40 MPH) (no brakes). Repeat this 3 times. Allows learning for the misfire monitor.
Readiness Check 12. Access the On-Board System Readiness (OBDII monitor status) function on the scan tool. Determine whether all non-continuous monitors have completed. If not, go to step 13. Determines if any monitor has not completed.
Pending Code Check and EVAP Monitor "Bypass" Check 13. With the scan tool, check for pending codes. Conduct normal repair procedures for any pending code concern. Otherwise, rerun any incomplete monitor. If the EVAP monitor is not complete AND IAT was out of the 4.4 to 37.8 °C (40 to 100 °F) temperature range in step #4, or the altitude is over 2438 m. (8000 ft.), the EVAP "bypass" procedure must be followed. Proceed to Step 14. Determines if a pending code is preventing the clearing of P1000.
EVAP Monitor "Bypass" 14. Park vehicle for a minimum of 8 hours. Repeat steps 2 through 12. DO NOT REPEAT STEP 1. Allow the "bypass" counter to increment to two.

 

Executing an OBDII drive cycle on an OBDI vehicle isn't likely to be useful....

If your inspector really does know his ****, he'd know that those O2 monitors have been calibrated out on the OBD1-level software programmed into Ford's 49-state Superduty trucks. He's going to have to do whatever procedure is necessary to account for this anomaly.

FWIW, my 01 F250 49-stater has never set those monitors in the 2+ years I've had it.

 

Thanks gents for leading me to a solution. Turns out my truck is a federal certified vehicle, with no egr valve, no downstream o2 sensor and needs a obd2 bypass. Took it into a test only center (California) and explained to the technician the above information and he looked at me kinda funny. I told him that he truck does not have a downstream o2 sensor and therefor the monitors could not set. He inputed the vin number of the truck and it stated that my vehicle is a obd1 truck and a bypass is needed. The tech actually called BAR and spoke to someone to verify. All is good, truck passed with flying colors. Now , for those of you not familiar with California's new star center requirements , Il try to explain it. Every smog shop now is on a rating and scoring system, they basically try to avoid any vehicle that might give them issues, because their score will drop. This explains the several smog shops that didn't even want to hear me out initially about my trucks monitors would never set. Just another way of big brother squeezing the life out of the working class by making stupid emmission regulations in California.

 

Glad that you finally found someone who would get it tested properly!
