Fuel Pump Resistance & Operation (Camry Gasoline Models, Camry Solara, Celica, Corolla, ECHO, RAV4, Tacoma & 4Runner)
Note. On Camry CNG models, fuel pump is not used.
- On Camry gasoline models, Camry Solara, Celica, Corolla and ECHO, remove rear seat cushion, cover plate on floor panel and remaining necessary covers for access to electrical connector for fuel pump.
- On RAV4, remove driver-side rear seat and cover plate on floor panel for access to electrical connector for fuel pump.
- On Tacoma and 4Runner, it may be necessary to lower fuel tank for access to electrical connector for fuel pump.
- On all models, disconnect electrical connector for fuel pump. This is electrical connector for fuel pump and fuel gauge sending unit and is located on top of fuel tank, near fuel pump.
- To test fuel pump resistance, using ohmmeter, check resistance between specified terminals on fuel pump electrical connector or fuel pump. (Scheme 37)- (Scheme 43). Replace fuel pump and/or lead wire (if equipped) if resistance is not.20-3.00 ohms at 68°F (20°C).
- To test fuel pump operation, apply battery voltage and ground to (+) and (-) terminals on electrical connector or fuel pump. (Scheme 37)- (Scheme 43). DO NOT apply battery voltage to fuel pump for more than 10 seconds. Replace fuel pump and/or lead wire (if equipped) if fuel pump fails to operate.
