Code 36
EGRC-BPT Valve Test:
EGRC-BPT VALVE FUNCTION (DTC: P0402)
Instead of performing DTC DETECTING CONDITION, the following method can be used for checking the EGRC-BPT valve function. (The "NG" of the OVERALL FUNCTION CHECK means the same as the DTC detection.)
1) Disconnect the rubber tube to intake manifold, which comes from fuel pressure regulator.
2) Disconnect the rubber tube to EGRC-BPT valve, which comes from EGR & canister control solenoid valve.
3) Connect the intake manifold and the EGRC-BPT valve with rubber tube installed 1 mm (0.04 in) diameter orifice. (The intake manifold vacuum will be directly applied to the EGRC-BPT valve.)
4) Start engine.
5) 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.
6) 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.
7) Check rubber tube between EGR & canister control solenoid valve and throttle body for bad connection, cracks or obstruction.
