Using a hand vacuum pump apply vacuum to the line while watching the voltage on the Violet/White wire. Voltage is supposed to change at approximately 1" Hg vacuum. Try testing this switch several times to see if the switch is sticking. Replace the NVLD if the switch is sticking.

I am not familiar with the aftermarket chip you are using. Could this be causing the problem? Yes! I would also check with the manufacturer of the chip.

3. At the Natural Vacuum Leak Detection (NVLD) assembly, which is located on top of the charcoal canister, which is mounted above the fuel tank, backprobe the Violet/White wire with a voltmeter. Locate the vacuum line going to the canister (from the purge solenoid) and remove that line so a hand vacuum pump can be used to put vacuum on the port going towards the canister/NVLD assembly. Block the other two lines at the canister.

[Wellstech]

1. Verify that the hoses for the purge solenoid are routed correctly and not pinched or restricted in any way. This includes verifying the lines to make sure there is no liquid fuel or charcoal in the lines. Clean as needed or replace the lines as needed.

2. Verify that the canister purge solenoid will vary duty cycle when commanded to by the scan tool. Replace the solenoid if sticking.

You are right it is a typo error. It should be P0455.
