EGR Gas Temperature Sensor: Tacoma
WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2003 Toyota Tacoma, 2003 Toyota RAV4, 2003 Toyota Prius, 2003 Toyota Matrix, and 2003 Toyota MR2. However, it is still accessible from the selected car via links, so may be relevant.
- EGR gas temperature sensor is located near EGR valve. Remove EGR gas temperature sensor. See EGR GAS TEMPERATURE SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL & INSTALLATION - 4-CYLINDER article.
- Place threaded end of EGR gas temperature sensor and thermometer in container of oil. Attach ohmmeter between electrical terminals on EGR gas temperature sensor.
- Heat oil and note resistance at specified temperature. See EGR GAS TEMPERATURE SENSOR RESISTANCE table. Replace EGR gas temperature sensor if resistance is not within specification. Reinstall EGR gas temperature sensor.
