Locating the data link connector

First of all you need to access the Engine Control Module (ECM) using suitable diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC's memored. DTC = Diagnostic Trouble Code. Then you will bu full informed about the root cause of the problem, and you will be able to repair & replace bad pieces and reset the ECM. Then the EPC (Electronic Pedal Control) yellow light will turn OFF.

What you are looking for are TERMINALS in the data link (check) connector. (see diagram below) The check connector is located near the No. 2 relay block on the right (passenger) side of the engine compartment. To check the timing on that engine you want to jumper the "T" and "E1" connectors.

1
Locate the 16-pin data link connector. Connect the jump wire to terminals 4 and 9 of the connector. Turn the key to the "On" position without starting the engine.
2
Watch the "Check Engine" light. This light will begin to flash in specific patterns to indicate a 1- or 2-digit Diagnostic Trouble Code. The flashes will be long for the first digit, short for the second digit and blank if the digit is 0.
3
Record all the codes given. The "Check Engine" light will display the codes in sequence and then keep repeating them in order. Refer to your repair manual to check for the meaning of the codes.

Hi Friend:

#1) I'm Putting a Diagram of your Firing Order up.1st.

Clockwise 1--3--4--2 On Distributor Cap

#2) Your Ingnition Timing , Make sure engines temp is at normal operating temperture, #3) Pull out Engine Service Connector, which is located behind RIGHT SIDE KICK PANEL .

#4) Now take a Jumper wire and Jump the BROWN WIRE with the GREEN AND WHITE Wire Terminals on the Connector.CAUTION: DO NOT JUMP THE 3PIN Data Link on Vehicles 1993 and Up.

#5) Now Connect Timing Light There is a Mark on your Bottom (Crankshaft Pully) Its Red in Color,NOTE: you might have to clean this up before even beginning anything.!

#6) But Look Down to lower Crankshaft Pulley the Timing Light should be Lined up to the RED Mark.Your Timimg Sets at 16 Degrees Before Top Dead Center and Idle should be 670 RPM

Please Let me Know the Quality of my Solution to Help You is By Voting and a Testamony Thanks For Using FIXYA From d_hubbs

The data link connector(dlc) is located at the dash end of the center
console behind the ash tray. Hope this helps.

How to Replace a Throttle Position Sensor
(DIY & Save up to $135.75 ) - Time: 2.1 hours

Parts:
1. Throttle Position Sensor - $ 55.44

Tools:
1. Scan Tool
2. Screwdriver
3. Multimeter

Procedure:
1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.

• Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.

2. Turn your key to the“ON” position. Do not start the engine.

3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).

Scanner plugged into OBD-II data link connector.

• Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  

• 4. Locate the throttle position sensor.

• 
  
• Throttle position sensor
  

• 5. Disconnect the electrical connector from the throttle position sensor.

• 
  
• Electrical connector removed
  

6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.

• 7. Remove the throttle position sensor.



Removing sensor mounting screws

8. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.

• 9. Erase the diagnostic trouble code (DTC) with the scan tool using the“delete” or“erase” command. Road test your vehicle to see if the check engine light returns.

• Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.

Direct OE replacement

Hope helped with this. Good luck (remember rated this help).

you need to connect the data link connectors underneath the steering wheel, then turn ignition on and count the flashes that the engine management light blinks..Post back
