Ya so anyway, i brought the truck to get the sticker put on. The guy plugs into the obd port to pull emissions and i get rejected due to computer not ready to be tested. The guy asked me if i recently unplugged my battery for any reason, i say no. The only thing i can think of is somehow the predator is messing something up and it's not allowing their scanner to work. Last time i used the predator was saturday at the track. The little print out they gave me said a few days of city/highway driving will correct this. I've driven a bit since saturday and it still failed. Anyone have a similar experience? If so what did you do about it?

 

it probably had a P1000 code stored in the PCM meaning that the vehicle hasn't completed a drive cycle since the codes were last cleared.

they reject you for this because the pcm controls and monitors all of the emissions controls.

if you had a faulty part and it was turning your check engine light on, some "unscrupulous" sp? folks might try to clear the code right before they take the vehicle in for testing so no trouble fault codes will show up.

whenever the codes are cleared, you get a P1000 until a drive cycle is completed.

same thing if you disconnect your battery.

I don't know if/how the predator could cause this unless you recently changed your program, or used it to clear codes.

good luck.

Same thing happened to me...

I just drove it for a week and took it back - In texas they have to give you the option to fix it yourself and then they retest for free...

 

Yea, i changed my tune on saturday at the track. I have never gotten an SES light ever in my truck. I'll drive it the rest of the week and bring it back next week. Thx for the info.

 

If it's anything the same as my old Silverado (which I'm sure it is) you just need to drive it several cycles and for at least 50 to 100 miles. I deprogrammed my truck and it failed smog once. Even though your putting your stock tune back into the truck it still needs time to relearn all of the systems it runs checks on. At least that's what a Chevy does. And after 100 miles of driving I took it back and it passed with flying colors. Hope this helps.

 

Here is the drive cycle procedure for an 2001 F150:

---------------------
OBDII Monitor Exercised Drive Cycle Procedure

1. Install scan tool. Turn key on with the engine off. Cycle key off, then on. Select appropriate Vehicle & Engine qualifier. Clear the continuous diagnostic trouble codes (DTCs) and reset the emission monitors information in the powertrain control module (PCM). Bypass engine soak timer. Resets OBDII Monitor status.

2. 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).

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.

-------------------------

you can ignore steps 1, 12, 13, and probably 14.

but you get the idea, there are quite a few requirements to complete a drive cycle.

thats why people say, "drive it for a week" and it'll be be ok. it has nothing to do with miles driven or hours driven, you just have to satisfy all the requirements, sometimes in order.

although it is theoretically possible that a person's driving style/habits would not complete all of these requirements and a vehicle could be driven for years without completing a drive cycle.

the requirements used to be more detailed, but were reduced for that very reason.

good luck.

screw that..........find a nice shop on a side street and flip them and extra 20 if it is emissions and not the predator. Thats what i did with my mustang..............cam, heads, vortech supercharged. Headers straight out the back. Yeah it passed.

Type in any auto shop in Brockton.

 

Since Ihad the service DVD I printed the steps above and spent about 3 hours on 2 days trying to force the steps to complete - monitoring the ODBII status with the NGS ... It simply wouldnt happen ... Its far less painful to just drive it and take it back .. PLUS - Not all of the ODBII tests from Ford need to be complete to pass in Texas - just a few key ones.. Mine still said testing incomplete on the NGS when I took it back to the dealer - I cant remember which sections were left ...

 

"I'll drive it the rest of the week and bring it back next week."

Keep checking for codes with the Predator. The P1000 will clear, THEN go back.

 

I've got 1,000 miles on mine since my last tweak to the pred and it still hasent cleared out!! I guess I'm in trouble huh?
Emissions here is ran @ state facilities so you cant get away with going to a local shop for a payoff!!

 

Like I said earlier in Texas you dont have to clear the entire p1000 code just the correct portions of it - The ODBII tests are run and complete individually. Once they have all run and completed then the P1000 goes away
