3.
Measure resistance between the terminals 1 and 2 of the EGR valve connector.
The EGR(Exhaust Gas Recirculation) system is used to add the exhaust gas to intake air in order to reduce an excess of air and the temperature in the combustion chamber.
The EGR valve is directly controlled by ECM's control signal directly not by vacuum.
ECM controls the EGR valve with duty.
The duty control of the solenoid valve is determind by ECM depending on engine load and the need of intake air.
Temperature℃(℉) | Resistance(Ω) |
19 ~ 25 (66.2 ~ 77) | 7.3 ~ 8.3 |
Turn the ignition key off.
Disconnect the EGR valve connector.
Measure resistance between the terminals 1 and 2 of the EGR valve connector.
Refering to "SPECIFICATION", check that the resistance is within specification.
