Overall Function Check




OVERALL FUNCTION CHECK
This procedure can be used for checking the overall function of the EGRC-BPT valve. During this check, a Diagnostic Trouble Code (DTC) might not be confirmed.
1. Disconnect the rubber tube to the fuel pressure regulator at the intake manifold.




2. Disconnect the rubber tube to the EGR & canister control solenoid valve at the EGRC-BPT valve.
Connect the intake manifold and the EGRC-BPT valve with a rubber tube that has 1 mm (0.04 in) dia. orifice installed. (The intake manifold vacuum will be directly applied to the EGRC-BPT valve.)
3. Start engine.
4. Check for the EGR valve lifting with engine at less than 1,500 rpm under no load.
