5. Research the ignition coil's potency service. With the ignition switch on, benefit a voltmeter to constitute certain there is battery voltage at the coil's certain terminal.
Instructions
Spark Test
1. Remove the Tacoma's ignition coils with the igniter from the Glimmer plugs, then remove the plugs. You must disconnect the spark plug wires from the plugs on a 3RZ-FE engine.
2. Install the Glimmer plugs to the ignition coil or Glimmer plug cables, attach the ignition coil electrical connector and disconnect the electrical connexion from Everyone fuel injector. Ground the spark plug to a metal spot on the engine.
3. Eccentric person the engine and eyeful for a forceful dejected Glimmer on the plug. Evaluation the connexion to the ignition coil and igniter provided no Glimmer appears.
If No Spark Appears
4. Study the Glimmer plug wires' resistence whether the Motor lorry has them. The resistence should degree 25,000 ohms on an ohmmeter. Interchange any wires that don't applicable specifications.
There are multiple ways to troubleshoot a Tacoma's ignition process for problems. The analysis you should perform antecedent involves testing the Glimmer plugs and wires. Whether they don't practise sparks, you must examination distinct other parts.
6. Measure the resistance of the ignition coils. Unplug all connectors and test the primary resistance between the positive and negative terminals. It should be 0.67 to 1.05 ohms.
7. Test the secondary resistance between the positive terminal and high-tension terminals. The resistance 9.3 to 16.0 kilo-ohms on a 5VZ-FE Tacoma engine and 9.7 to 16.7 kilo-ohms on the others.
8. Use the ohmmeter to check the camshaft position sensor's resistance. Measure between the G+ and G- terminals on the sensor connector. The resistance should be One hundred eighty five to Two hundred seventy five ohms on a 2RZ-FE engine and Eight hundred thirty five to 1,400 ohms on the rest.
9. Move to the crankshaft position sensor, measuring the resistance between its connector terminals. It should measure 1,630 to 2,740 ohms.
10. Look over the wiring between the engine control module and the igniter. If the wiring is okay, the problem is likely the igniter.
