Code 36

Instead of performing DTC Detecting Condition, the following method can be used for checking the EGRC-BPT valve function.






Overall Function Check

1. Disconnect the rubber tube to intake manifold, which comes from the fuel pressure regulator.
2. Disconnect the rubber tube to EGRC-BPT valve with rubber tube installed 1mm (0.04 in) diameter orifice. This will directly apply the intake manifold vacuum to the EGRC-BPT valve.
3. Start engine.
4. Check for the EGR valve lifting when racing at lower than 1,500 rpm under no load. EGR valve should be closed and should not lift up.
5. Check the EGR valve lifting when racing up to 2,000 rpm through 4,000 rpm under no load. EGR valve should lift up and down without sticking.
6. Check rubber tube between EGR & canister control solenoid valve and throttle body for misconnection, cracks or obstructions.

Component Inspection






1. Plug one of the two ports of the EGRC-BPT valve.






2. Apply vacuum to the other port and check leakage without applying any pressure from under the EGRC-BPT valve. Leakage should exist.
