I have a '03 6.0 auto 4X4 CC

Yestarday on the way to work the engine light came on, about 20 minutes into my drive. I got to work and hooked up the scanner and it had no codes and the light also didn't come back on when I restarted. I put about 50 miles on the truck after that and the light never came back on.

Today about the same point into my drive to work the light came on again. This time when I got to work I put the code scanner on it and it showed the following codes:
-P1000 OBD II System readiness test not complete
-P2263 Turbo Charger Boost system performance

The truck seems to be running fine though. I reset the light this morning. Anyone know what this is or how to fix it?

 

OK I now know what the P1000 code is from reading another post.

Anyone with input on the P2263?

OK thanks to google I know that P2263 is: "Fault sets if MAP does not exceed 15KpaG" It looks like it normally comes from long idle. Problem is mine came on from driving down the road.

 

can you link to the thread or say what the P1000 code is/does? i was getting it before as well and am not sure. wish i could help on the turbo, good luck.

 

It is the thread about the Banks 6 gun melting 2 cylenders on a 6.0

P1000 is basicly the computer saying that it hasn't gotten enough data to say that everything is working OK. I think mine may have came from resetting the codes without driving the truck so that the computer knows that it is all OK.

I just typed OBD + "whatever code it is" into google and it brings them right up. Something I noticed is that lots of cars must run the same program because the codes mean the same thing on several different makes.

 

OBD2 was designed to set standard codes for engine functions. The engine and emission related codes will stand for the same type of problem on all vehicles.

 

OK but what caused the P2263 code to come up on me?

 

You had any flashes on that 03? Seems I remember a TSB on false P2263 codes.

Here it is:

Low Power/No Boost and/or Code P0299 or P2263:
If the turbocharger is suspected to be the cause of low boost, it should be tested by manually activating the variable geometry turbo control valve. The engine should be at operating temperature. Using the WDS active commands in datalogger, monitor EBP, VGT%, RPM abd MGP. Set the RPM to 1200 and the VGT% to 0 and record the EBP and MGP readings. Increase VGT to 85% and watch for an increase in EBP and MGP, and listen for a whistle from the turbo. If there is no pressure increase or whistle, check the control wiring for the VGT by installing a est light in the VGT harness and commanding the VGT from 0-85%--the light should be off and then slowly brighten. If the wiring checks out, replace the VGT control valve (P/N 3C3Z-6F089-AA) and retest. If the condition is unchanged, then replace the turbocharger. Broadcast Message 0887.
Engineering is currently investigating false P2263 codes. Broadcast Message 1290, 3005

Take it in.

Here is another:

Rough/Surging Idle, Excessive Smoke, Lacks Power, Poor Throttle Response:
This may be accompanied by DTC P2263. Inspect all intercooler hoses and pipes and exhaust system before the turbo for leaks. Ensure the oil level is correct there are no oil leaks and all electrical connectors are secure. Check the ICP sensor as in the following bulletin. If no problems are found, make no attemp to repair the condition. Engineering is investigating. Broadcast Message 0225, 0471. SSM 16488.

 

P1000 means that the diagnostic monitors (readiness) are not reset, and reading codes/DTC test won't be available until relearned.. Either a scanner code clearing/programmer change/battery disconnect or dead/drain will clear the KAM..

The 12/12/03 (RC7/49 state) flash will turn out the P2263 DTC for code/false codes if it applies to your truck..

I cleared the code and put about 75 miles on the truck today. No more light. Odd that it came on twice at sort of the same point in my drive to work. If it keeps up I will take it in. It was flashed sometime the summer of '04.

HAYAPOWER that is a sweet car. I bought my wife a 30th anniv. TA convertible for her 30th birthday in 99. Would love to get a 69 to match. Been thinking of getting a 69 Firebird convertible and making a clone TA for her 40th birthday here in a few years.

 

NICE present!

I wanted a 99 too, actually looked a round a bit when they first came out, and off n' on later, but settled for the truck instead!! Needed some way to pull it to the shows..

This how to get rid of the P1000 after the KAM is cleared. It is calle Drive Cycles. This is right out of the PowerTrain Control Manual.

Drive Cycles
OBD Drive Cycle
Description
The primary intention of the OBD Drive Cycle is to clear the DTC P1000 and to satisfy the specifications for SAE specification J1979. Each OBD monitor must run during the drive cycle.

If the drive cycle is completed and P1000 is not cleared, repeat the entire drive cycle. If a particular step is interrupted, simply repeat the drive mode. If the drive cycle is interrupted with a key-off, only drive modes that were incomplete must be run.

CAUTION: Strict observance of posted speed limits and attention to driving conditions are mandatory when proceeding through the drive cycle.

Rough road conditions may prevent certain steady state conditions and steady accelerations from validating the transmission- and load-related monitors.

Vehicles equipped with Power Take-Off (PTO) must have that system disengaged before the OBD drive cycle is initiated.

Drive Cycle Procedure:
Key on. Do not crank until the WAIT TO START light cycles, or at least 10 seconds, whichever is greater.
Start the engine. Idle in PARK or NEUTRAL for 40 seconds.
The following outlines the appropriate conditions for running certain OBD monitors that require the engine to be under load:
Accelerate steadily to third gear (M/T use fourth gear) and hold at 1500 rpm for 3 seconds. Accelerate steadily from 35 mph to 65 mph over approximately 15 seconds (M/T 11 seconds minimum).
Repeat Step 3a three times while maintaining the conditions in Step 3a.
Before proceeding, turn all accessories off and disengage tow/haul.
Before continuing, EOT must exceed 60°C (140°F).
Idle the vehicle for 20 seconds in PARK or NEUTRAL.
Key off.
Start the engine. Idle in PARK or NEUTRAL for 40 seconds.
Rerun Quick Test.
Note: If P1000 is present after running the drive cycle:

Rerun Step 3a, being certain to maintain a minimum MFDES of 35 mg/stroke above 2,000 rpm for 11 seconds. Also, maintain a minimum MFDES of 30 mg/stroke above 2,800 rpm for at least 6 seconds.
Rerun Step 8. MFDES must remain below 12 mg/stroke for 11 consecutive seconds.

 

Where can I get a code reader and which Brand is best...My Check Engine light has just come on at 10,000 miles and I feel nothing wrong with the truck...I checked for water and found none, rechecked fuel cap, and used the old trick with my 96 (gas) and disconnected the batteries for 30 seconds and put everything back in service...The dash went thu it's check prior to starting and everything was good with the truck but the check engine icon is still on...Any help is appreciated...
