How to:ECU Reset,Throttle & Accelerator Position Learning - Page 6

Brianyzf · 09-30-2008, 09:04 AM

I can't get my ECU to reset in my '04. I've tried the easy method about 20 times over two days now and still no luck. I just can't get the SES light to blink. I've used this method before and had success but something's wrong this time. And after every time I try and fail, when I step on my brake pedal in order to put the truck in drive the pedal is really spongey and goes all the way to the floor while making a sound like air releasing. I was afraid that I had no brakes but once I start to drive the pedal feels normal and the brakes work fine. Anyone have any thoughts on what might be happening?

I tried this and after i hold the pedal down for 10 seconds the SES starts to blink but then stops after a few seconds. Should I try holding the pedal down longer? Anyone have an idea why the SES light does not continue to blink?

If you only get 3 sets of 10 blinks, the ECU has no codes. If it starts to blink and then stops, there could be a problem with the communication between the ECU and SES dash light. Be sure you do not hit the accelerator or turn the key or the test will stop.

Guys, i need some help. Tryed to reset my ecu yesterday and couldn't get my check enging light to blink so i tryed it again. Now i have a blinking red light with a wrench in the center of it just above my speedometer. I've read the owners manual and can't find the purpose of this light. Can anyone identify this light and can i clear it? I think the reason i couldn't reset the ecu is because i have a active tire pressure light. thanks

Tire pressure light doesnt matter. I dont have mine in my aftermarket rims so its always on. Try the procedure with a stopwatch. do the one called the "easy method". Time isnt as criticle. or go to autozone and get the code read and cleared for free. If the light was on before you should read it first rather than clear and ignore.

It is better to count the time accurately with a clock.

Operation Procedures

1. Perform “Accelerator Pedal Released Position Learning”.
2. Perform “Throttle Valve Closed Position Learning”.
3. Start engine and warm it up to normal operating temperature.

...

You've got to be kidding me. This procedure was posted almost three years ago and nobody has noticed it's incorrect yet?

Step 3 is NOT how to prepare for the Idle Air Volume Learning procedure.

RTFM!

Reset my ECU last night, and the truck seems to be idling better, and seems to have a little more low end power. Thanks for posting this Info!

you sir are wrong. check the service manual yourself, OP is correct.

Does this information still apply and work even on newer models? This thread was started a while ago.

oops, i take that back, i should of went to the last page.....it was updated only a few days ago

Yep, i just did all of it yesterday. The only problem I had was after I did the Idle Air Volume Learning (Throttle Position Learning), when i started my truck, every time i rev'ed up the CEL flashed. But after restarting it that problem went away and everything's fine and reset now.

i guys i am new on this forum i just put a con air filter and i wondering if reseting the ecu will do a good think or it will be a wast of time
An also i want save some money a the pump i will install un hho generator an some guys did not get the milage saving because they did not install oxy extender or lamba/efie to fool the co2 sensor so ?
my question is by reseting the ecu! do you think the ecu will ajust to run with HHO gaz? like the this guy on youtube said
thank you in advance to reply

The ECU will learn your new filters increased airflow. If you want to do the ECU Reset do it with the gas pedal method, the battery needs to be disconnected for 8+ hour for the Titan ECU to reset.

stef12r · 12-03-2009, 06:23 AM

ok thank i did reset the ecu by the gas pedal for my filter !
but the hho do you think it will be possible that the ecu will learn?
