In my case, the VTM-4 light never comes on from cold and does not usually come on until the engine is warm. It does come on when the engine is warm but the transmission is cold (e.g. remote start in driveway, warming up but not driven… not even shifted out of park).
What causes a check engine light with a P0420 code?
In most cases, a P0420 code is caused by a bad catalytic converter. You will probably not have any symptoms except the check engine light with just the P0420 code stored. You may have other problems with your engine damaging the catalytic converter, which can cause symptoms like rough idle, rough acceleration, misfires, and hard shifting.
What does P0420 mean on a catalytic converter?
P0420 means that the efficiency of the catalytic converter is below the threshold. The ECM uses two O2 sensors, one in the front and one in the back of the catalytic converter to measure the efficiency. If the efficiency is low, the P0420 code will be triggered.
When does the VTM-4 warning light come on?
Yes….the VTM-4 module de-activates 4 wheel lock when the warning light is on steady or blinking. If blinking, park it right away per owner’s manual. I received the part from collegehillshonda. Yesterday my mechanic installed it. Today I took a 350 mile trip and the light DID NOT come on.
What causes the O2 sensor to show the code po420?
Rich or lean mixtures can damage the catalytic converter, and when the catalytic converter is damaged/filled with fuel, the efficiency will be low, and the rear O2 sensor will see that and show the trigger the code Po420.

The VTM light means Variable Torque Management. Chances are there is a code or several codes in the computer causing this light to come on. To retrieve codes, ground the Brown wire in cavity #9 of the OBD-II connector and turn on the key on and the VTM-4 light should flash out the problem codes.
