How is the P0420 oxygen sensor simulator hack?
Here’s how to diagnose and hack around the P0420 Inefficient catalytic converter code on a Honda. The catalytic converter’s performance is measured by the secondary Oxygen sensor. If the output is less than 95% it throws the P0420 code.
What do you need for an O2 simulator?
By “working” I mean that all you have to have is an O2 sensor that’s putting out some kind of signal.
How much does a rear O2 simulator cost?
DO NOT DO THIS MOD TO YOUR FRONT OXYGEN SENSOR. ONLY DO THIS TO THE REAR ONE. This should cost around $5 or $6. Step 1: This step isn’t required, but it will make things easier. Unbolt the rear oxygen sensor from the exhaust pipe, which is held on by two 12mm nuts.
What to do with the rear O2 sensor?
With the rear O2 sensor completely removed, you can modify it on your work table or where ever you want, instead of cutting and splicing while underneath your rig. Step 2: Cut the blue and white wires on the oxygen sensor.

How much does it cost to make an O2 simulator?
This method may not work if your o2 sensor is too far gone, in which case you can buy a 555 timer based o2 simulator which generates a signal independent of the o2 sensor output, but that costs $20-40 and you have to mail order it. This $3 solution is easy if you’re good with a soldering iron and worth a try.
How can I fake an O2 sensor on my car?
Install the dummy O2 sensor (also called an O2 sensor simulator) by turning it clockwise into the exhaust just as though you were installing a regular O2 sensor. Connect the electrical wiring to the dummy sensor. Lower the vehicle to the ground and start the engine.
