What is the procedure to check the ignition timing on a 2003 Tacoma, 2.4l?

 

Well, you'll need a dead chicken, two gallons of wombat blood and a large rat.

J/K

Here's the procedure:

1. Connect a Tachometer to the the IG terminal inside the Diagnostics connector in the engine compartment. Connect the other two leads of the Tach to the battery.

2. Locate terminals E1 and TE1 and short them together with a small piece of 18G wire that has the ends stripped.

3. With the ignition switch off, connect a timing light. An inductive timing light would be best. You'll need to know how to connect your particular light.

4. Locate the timing marks on the Timing cover and on the crankshaft pulley. Clean them if necessary.

5. Start the engine and allow it to warm up to normal operating temperature. Verify that your idle speed is correct, it should be about 650-750 RPMs.

6. Aim the timing light at the marks and check the timing. It should be 3-7* BTDC. If it is between 4-18* BTDC, you don't have E1 and TE1 shorted.

7. If it is out of spec, loosen the distributor hold-down bolt and slowly rotate it until the marks line up. Tighten the bolt on the distributor.

8. Once adjusted, turn engine off, remove the jumper from E1 and TE1, disconnect the Tach and timing light.

9. Done

Hope this helps.

 

thanks, man... i thought i remembered something about shorting e1 & te1 on my '89 4x. but since then my alzheimer's has flared up.

 

Doesent the 2003 2.4 have coil over plug and no distribitor?

 

I have a 97 tacoma 2RZFE and that is absolutely wrong. The truck distributor is not manually adjustable with a timing light. Supposedly, if you line everything up right to TDC the crankshaft position sensor and camshaft position sensor are supposed to communicate with the ECU and the ECU is supposed to adjust your timing. Toyota really sucks!!!!
