CHECK ENGINE LIGHT: '95 VW JETTA

Check engine light is on steady. Using the following procedure: Turn iginition key to ON, don't start. Jumper betweeen pins 4&15 on the plug located behind plastic cover next to ash tray. Hold jumper in place for 4 seconds. When jumper removed the codes should flash. All I get is after 4 seconds the light goes out and don't get any codes. Is the procedure I'm using wrong or did I skip a step???

That only works on old OBD 1 computers - unhook your battery for a couple hours - that might put your computer back to default and you can take it to auto zone and have them scan your computer for free.

How to check for bad check engine light on volkswagon jetta


The check engine light should come on along with the rest of the warning lights as a test when you turn the key switch on.
They should then go off once the engine starts.

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.

1994 vw jetta no fuel and ignition


It sounds like you may need an ignition contact block. It turns everything on. If all the idiot lights come on when you turn the key to on. Then move the key to start the engine. Note the engine can turn over but no ignition power or fuel can be do to the contacts in the block. Take notice if the idiot lights stay on, or turns off when you crank the engine to start. The lights should stay on.
The contact block is not an easy fix and can take a few hours. The procedures are found online. Steve

Jetta headlights not working


Ignition switch will cause you to loose your head lights and turn signals. You will still be able to start the car and hold the switch for your brights but normal function is gone. Check it out it usually only runs about $20-$30 for replacement part but you need a special puller to get to it.
