Question about 2002 Mercedes-Benz M-Class

Open Question

My 2002 ML320 won't accelerate (pedal to the floor) for up to 5 seconds, then gradually accelerates, and seems fine until I stop again. I have had it serviced twice in the last two weeks because of this issue. After a day or two, it occurs again. I have spent just under $3000 in new parts and labor to fix this to no avail. I'm at my wits end. Please help!

SOURCE: My 2003 Nissan Altima won't accelerate.

The accelerator is a potentiometer connected to a pedel and the wires go directly to the ECM. If the AWU( accelerator Working Unit) was bad the engine would run constant at 1800-200 rpm. Do any codes come up? I will do some more research and repost.

Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

SOURCE: loud chirping noise when acceleration pedal is

There is a TSB (Technical Service Bulletin) for this problem:

Engine - Accessory Drive Belt Noise Diagnostics/Tool
08-06-01-008 03/27/2008
This particular vehicle had an issue with pulley alignment, particularly the power steering pulley. Take a look at the shaft the pulley is pressed onto. If the end of the shaft isnt flush with the pulley, it is out of line and will cause a squeal.

It is recommended that you discuss this TSB with your dealer (not local mechanic).

I hope this helps.

The change oil light came on. on my friends 2002 monte carlo ss so i gave it an oil change and a new filter . the light won't go off.


The "Oil Change Reminder Light" has to be reset.

To reset the oil change reminder light with the accelerator pedal, turn the ignition switch to the ON position. Do not start engine. After turning the ignition ON, depress the accelerator pedal fully to the floor and let it up again 3 times within 5 seconds. The oil change reminder light should flash a few times to let you know that it is resetting. If it does not flash, turn the switch OFF and repeat the procedure. After it flashes, turn the ignition switch OFF. Then start the engine. The light should come on for a bulb check then go out and stay out.

Stops while driving


this is usually due to a dirty throttle body. just beware if you do try to clean it you will need to preform the idle relearn procedure. this does work, ive done it personally.

A. Accelerator Pedal Release Position Learning Procedure.
1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds (how would you know if you get it right?)


B. Throttle Valve Closed Position Learning
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is “ON”.
3. Turn ignition switch is “OFF” wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound (i never get this right because i never heard anything)

C. Idle Air Volume Learning (Throttle Position Learning)
It's best to time with a watch/clock.

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.
4. Turn ignition switch “OFF” and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops
blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11 Wait 20 seconds
12Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications. (this is fine because SES light lets you know if you did it right the way it blinks)
