EGR Boost Control Solenoid: Testing and Inspection
Simulation Test1. Carry out the "EGR Control Inspection". (Refer to EGR Control Inspection.)
Testing and Inspection
- If not as specified, perform the further inspection for the EGR boost sensor solenoid valve.
Airflow Inspection
NOTE: Perform the following test only when directed.
1. Disconnect the negative battery cable.
2. Remove the EGR boost sensor solenoid valve.
3. Inspect airflow between each port under the following conditions.
- If not as specified, replace the EGR boost sensor solenoid valve.
- If as specified but the Simulation Test is failed, inspect the vacuum hoses for improper routing, kinks or leakage, and inspect for the following and repair or replace the parts if necessary.
Open circuit
- Ground circuit (EGR boost sensor solenoid valve connector terminal B and PCM connector terminal 98)
- Power circuit (EGR boost sensor solenoid valve connector terminal A and main relay connector terminal D through common connector)
Short circuit
- EGR boost sensor solenoid valve connector terminal B and PCM connector terminal 98 to ground
4. Install the EGR boost sensor solenoid valve.
5. Connect the negative battery cable.
