EGR Position Sensor (Camry & Camry Solara)
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2003 Toyota Tundra, 2003 Toyota Tacoma, 2003 Toyota Sienna, 2003 Toyota Sequoia, and 2003 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
EGR position sensor may also be referred to as EGR valve position sensor.
- Disconnect electrical connector at EGR position sensor. EGR position sensor is located on top of EGR valve. See Fig 1.
- Using ohmmeter, check resistance between terminals E2 and VC on EGR position sensor. See Fig 1. Resistance should be 1500-4300 ohms. If resistance is within specification, reinstall electrical connector on EGR position sensor and go to next step. If resistance is not within specification, replace EGR position sensor. See EGR POSITION SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL & INSTALLATION - V6 & V8 article.
- To test EGR position sensor output voltage, disconnect vacuum hose from EGR valve. Remove glove box for access to Engine Control Module (ECM). Turn ignition on. Using voltmeter, check voltage between ECM terminals E2 (Brown wire) and VC (Yellow wire). See Fig 2 and Fig 3 . Voltage should be 4.5-5.5 volts. Remove voltmeter.
- Connect voltmeter between ECM terminals E2 (Brown wire) and EGLS (White/Green wire). See Fig 4 and Fig 5 . Using vacuum pump, apply 5.1 in. Hg of vacuum to EGR valve and note voltage. Voltage should be 3.2-5.1 volts with vacuum applied on EGR valve. Release vacuum from EGR valve and note voltage. Voltage should be.4-1.6 volts with vacuum released from EGR valve. Replace EGR position sensor if voltage is not within specification. See EGR POSITION SENSOR under ENGINE SENSORS & SWITCHES in REMOVAL & INSTALLATION - V6 & V8 article. Remove vacuum pump and reinstall vacuum hose on EGR valve.
