How do you read a computer on an 1986 toyota pickup


Jumper the TE1 terminal to the E1 terminal in the diagnostic connector with the ignition switch on and the check engine light will flash the codes. I think the diagnostic test connector is under the hood on the drivers side near the strut support and air filter box. It has a hinged plastic top about 3/4" x 1-1/2" in size. the terminal labels are inside the cap.

Ignition timing for 1989 toyota corrolla


1988-95 MODELS
See Figures 6, 7, 8, 9, 10 and 11
This service procedure is for setting base ignition timing. Refer to underhood emission sticker for any additional service procedure steps and/or specifications.
These engines require a tachometer hook-up to the check connector-see illustrations. NEVER allow the tachometer terminal to become grounded; severe and expensive damage can occur to the coil and/or igniter.
Some tachometers are not compatible with this ignition system, confirm the compatibility of your unit before using.
  1. Warm the engine to normal operating temperature. Turn off all electrical accessories. Do not attempt to check timing specification or idle speed on a cold engine.

Fig. Fig. 6: Attach the tachometer to the battery and check connector terminals

  1. Connect a tachometer (connect the tachometer (+) terminal to the terminal IG- of the check connector) and check the engine idle speed to be sure it is within the specification given in the Tune-Up Specifications chart or underhood emission sticker.
  2. Remove the cap on the diagnostic check connector. Using a small jumper wire or Special Service Tool SST 09843-18020, short terminals TE1 (test terminal No. 1) and E1 (earth-ground) together.
  3. If the timing marks are difficult to see, shut the engine OFF and use a dab of paint or chalk to make them more visible.
  4. Connect a timing light according to the manufacturer's instructions.

Fig. Fig. 10: Timing marks 4A-FE and 7A-FE engines

  1. Start the engine and use the timing light to observe the timing marks. With the jumper wire in the check connector the timing should be to specifications (refer to underhood emission sticker as necessary) with the engine fully warmed up (at correct idle speed) and the transmission in correct position. If the timing is not correct, loosen the bolts at the distributor just enough so that the distributor can be turned. Turn the distributor to advance or ****** the timing as required. Once the proper marks are seen to align with the timing light, timing is correct.

Fig. Fig. 11: If necessary, loosen the 2 mounting bolts and turn the distributor to adjust the timing

  1. Without changing the position of the distributor, tighten the distributor bolts and double check the timing with the light (check idle speed as necessary).
  2. Disconnect the jumper wire or Special Service Tool (SST) at the diagnostic check connector.

This jumper will be used repeatedly during diagnostics in later sections. Take the time to make a proper jumper with correct terminals or probes. It's a valuable special tool for very low cost.
  1. Refer to the underhood emission sticker for timing specification and any additional service procedure steps. If necessary, repeat the timing adjustment procedure.
  2. Shut the engine OFF and disconnect all test equipment. Roadtest the vehicle for proper operation.

Check engine light


It means that there is a malfunction with the engine control system which is most likely related to the emission control system, the computer stores some diagnostic trouble codes that should be retrieved, the trouble code numbers will help to find where the problem may be. The way to get the trouble codes is by putting a jumper wire in the diagnostic connector under the hood between the terminals TE1 and E1 with the key on the check engine light will blink the code, for example a code 24 would be two blinks followed by four and so on. Once the codes are known you can reply back to me and I can help further.

How do i check a code on my 93 toyota pickup without a scaner


If you tell me which engine you have, I can also provide the code list.
1989-95 MODELSjturcotte_2396.gif

  1. Make sure the battery voltage is at least 11 volts.
  2. Make sure the throttle valve is fully closed.
  3. Place the gear shift lever in Neutral. Turn all accessories off.
  4. The engine should be at normal operating temperature.
  5. Using a jumper wire, connect terminals TE1 and E1 of the Data Link Connector 1 (DLC1).
  6. Turn the ignition switch ON , but do not start the engine. Read the diagnostic code by the counting the number of flashes of the malfunction indicator lamp.
  7. Codes will flash in numerical order. If no faults are stored, the lamp flashes continuously every 1 / 2 second. This is sometimes called the Normal or System Clear signal.
  8. After the diagnosis check, turn the ignition OFF and remove the jumper wire.
  9. Compare the codes found to the applicable diagnostic code chart. If necessary, refer to the individual component tests in this section. If the component tests are OK, test the wire harness and connectors for shorts, opens and poor connections.

I have a 92 toyota pickup with the 3.0 v6 in it and the check engine light is on constantly. I was told that I could use a paper clip to tell me the codes, but i'm not sure which wires to jump. Anyone...


Locate the diagnostic check connector under the hood, it's near the right front fender close to a fuse box and it says "diagnostic" on it, open the cover, there is a terminal diagram inside it, put a jumper wire between the terminals TE1 and E1, turn the key on, the engine light will start blinking, if there is a trouble code the light will blink a two digit code number, for example a code 25 would be two blinks followed by five and so on, there may be more than one code, let them repeat a few times to get the correct information.

Engine check light on how to solve the problem


most toyotas you have to bridge terminals TE1 and E1 with a jumper wire or paper clip of the diagnostic connector.Found either near the left shock tower (in the engine compartment), next to the master cylinder,or near the fuse/relay box (also in the engine compartment) After you bridge the terminals, you turn the key to the on position, and count the number of flashes of the check engine light. This will indicate the trouble code #. P.S. I have always found Autozone.com to be quite helpful. You can enter your yr/make /model and view online Chiltons manuals. For Free. Good Luck.

How do you time a toyota 4 runner 3.0?


22r-E, 3vz-E And 3f-E Engines

  1. Warm up the engine, then turn it OFF. Connect a timing light to the engine following the manufacturer_s instructions.
  2. Connect a tachometer to both battery terminals. Connect the tachometer probe to the IG-terminal in the check connector box. The check connector box is located next to the underhood fuse and relay box on trucks and 4Runner's; for Land Cruisers, the check connector box is on the firewall. Use the correct adapter to insure a tight fit on the terminal. Not all tachometers, particularly older ones are electrically compatible with this system. Read instructions for your unit before using.

Attach the tachometer as shown

3. Start the engine and run it at idle. Check the idle speed on the tachometer; adjust it to specification if necessary.

4. At the check connector, use a small jumper wire to short the connector at terminal T or TE1 and terminal E1, of the DLC1 as shown. Special service tool (SST) 09843-18020 or its equivalent can be used for this also.

Connect the SST or jumper wire to the TE1 and E1 terminals of the DLC1

This jumper will be used repeatedly during diagnostics in later sections. Take the time to make a proper jumper with correct terminals or probes. It's a valuable special tool for very low cost.
  1. Check the idle speed, then check the ignition timing. The 22R-E should read 5° BTDC, 3VZ-FE should read 10° BTDC and the 3F-E should read 7° BTDC. All of these readings are at idle.

On 3-FE engines, remove the rubber plug at the rear of the engine to view the timing mark

On other engines, the timing mark is visible on the crankshaft pulley

  1. Loosen the distributor pinch bolt just enough that the distributor can be turned. Aim the timing light at the marks on the crankshaft pulley (or the drive plate on 3F-E) and slowly turn the distributor until the correct timing mark aligns with the pointer. Tighten the distributor pinch bolt.
  2. Remove the jumper wire or special service tool (SST) from the DLC1.
  3. Check that the ignition timing advances. At idle the 22R-E should read 10°-14° BTDC, 3VZ-FE should read 8° BTDC, and the 3F-E should read 12° BTDC.
  4. Shut the engine OFF and remove the timing light and tachometer leads.

"check engine" icon is lit


First verify that battery is fully charged (>11volts), the throttle is closed, the transmission is in neutral, and all accessories like radio/fan/defog/etc. are off. The engine should be warm but not running with key off. Under the driver's seat there is a diagnostic connector box. Flip open the cover and on the inside of the cover you will see a chart of the terminals. Use a small jumper wire (or a paper clip) and connect the TE1 and E1 terminals together. Now turn ignition switch to on with key but do not start. Check engine light will now blink code(s), for example: three blinks followed by a pause and then two blinks is the code 32. Copy down the codes and check back here. The code(s) will repeat in order until you turn key off. Don't forget to remove the jumper wire before driving.
