Question about 2002 Chevrolet Impala

1 Answer

2002 Impala 3.8

Hi!
I just wanted to thank you for the information about re-setting the computer using the gas pedal or the radio. You have been extremely helpful to me today. Another problem I am having is that the car starts fine for 2,3,4 months then all of a sudden it won't start 3 ties in one week. This has frustrated me for about 5 years and no dealership seems to know what the problem is. Can you help? My email is: philjones53@hotmail.com
Many thanks

Hopefully someone else with the same problem may read this. I already sent this person an e-mail detailing the solution but here goes. Chevy has a factory alarm system on the Impalas and some other Chevy products called Passlock or Passlock 11. Sometimes the system senses an intrusion (even when there is not one) and locks down the injectors. A fix for that moment is to leave the keys in the ignition in the ON position for 10 minutes and it should start right back up. To permanently fix this problem, you will need about an hour maybe less
The dash is held in place with clips and screws that once you get to looking at it are not that intimidating. Once you have the dash removed, under the steering column there is a metal plate that also needs to be removed, (couple of bolts). Once the plate is removed you should notice there are (3) wires coming up the steering column and they should be fastened or harnessed together some kind of way. One is grey, the other is yellow and if I remember correctly the other is white. For this problem the important one is the yellow. You should have some electrical tape or something to top off the ends of the yellow wire sitting there ready to go before you begin. Once you have located these wires (It will be the only bundle under the column that has 3 together) You will need to START the car, this is very important because the car needs to be running while you do this. Once the car is started snip the yellow wire making sure that the ends do not touch anything and short anything out. Cap each end of the yellow wire with electrical tape or something similar. Turn the car off and put everything back together. The security light which is orange or yellow will stay permanently on but it will not cause a problem other than being on. You can remove the bulb by taking out the control panel but trust me that is a lot more trouble than most people are willing to go to.

How to reset the oil change light on a 2002 chevy impala


It should be in your owners manual. On most models you either depress the gas pedal three times or go into the settings thru the radio controls to reset the oil change reminder.
Let me know if you need me to cut and paste the directions.

Came up with a code P1680 , can you tell what that mean's . Thank you


P1680 is Control Module Accelerator Pedal Position (APP) System Performance. Your car uses "fly by wire" meaning that when you press the gas pedal, there isn't a cable but rather a sensor that detects how far your pressing the pedal. that information is sent to the computer and in turn sends a signal to the solenoid at the intake manifold to open up. your problem is probably in the pedal assembly.

I just changed the oil in my 2002 Impala LS and filled the tires to the proper psi but the message center still reads both messages.....change engine oil..........tire pressure low. What do I need to do to...


ok this can be done 2 different ways 1 , with the radio controls , should be in the owners manual , or the easier way , to reset the oil maintinence light , turn the key to the ON position , engine OFF , depress the gas pedal to the floor 3 times within 5 seconds and it will reset ,

now the tire monitor system , same deal should be in the owners manual , and done with the radio controls , or the easier way , turn key to ON position , engine OFF , cycle the parking lights 3 times within 5 seconds , (turn on - turn off = 1 cycle)

pretty cool huh? but make sure your tires were properly inflated before you reset the tire monitoring system .

Can u reset oil,tire,ect...without original radio on a 2001impala


You should be able to reset the oil life light.
TRY this...
put the key in and turn to the accessory point,do not start the car.
Once you get to "acc" on the ignition press down 3 times on the gas pedal but NOT fast,sort of slowly.
Turn it off then start the car,it should reset and the light goes off if not..repeat it.
Always works for me.
I hate the reminder set up,stupid if ya ask me,i know when to change oil etc.
