Overall Function Check
Use this procedure to check the overall function of the EGRC-BPT valve. During this check, a 1st trip DTC might not be confirmed.
Without CONSULT
1. Disconnect the rubber tube to intake manifold collector at the EGRC-solenoid valve.
2. Disconnect the rubber tube to the EGRC-BPT valve at the EGRC-solenoid valve.
3. Connect two rubber tubes disconnected in steps 1 and 2. (The intake manifold vacuum will be directly applied to the EGRC-BPT valve.)
4. Start engine.
5. Check for the EGR valve lining with engine at idle speed under no load.
EGR valve should remain closed.
6. Check the EGR valve lifting when revving from idle up to 3,000 rpm under no load.
EGR valve should lift up and go down without sticking when the engine is returned to idle.
