Used to fix various error codes for the downstream Oxygen Sensor systems on modified cars. Offroad use only!
Whether your car has a de-cat, the engine is modified or it's just showing its aging catalytic system, the P0420 and P0430 (and many other) error codes can be very annoying and can cause various limp modes or some vehicle systems to be disabled.
We've designed our O2 sensor emulator to be Plug-and-Play directly on the wiring loom where the rear O2 sensor is connected. Currently offered with wiring suitable for most Toyota/Lexus vehicles (soon we'll introduce more types of plugs). If your O2 sensor plug looks like the one in the photos, then our emulator will most likely work transparently.
- Prevents the P0420 and P0430 Catalyst System Efficiency Below Threshold codes (for B1S2 and B2S2);
- Prevents the P0141 and P0161 Heater Circuit Malfunction error codes (for B1S2 and B2S2);
- Prevents the P0136 and P0156 Oxygen Sensor Circuit Malfunction error codes (for B1S2 and B2S2);
- Prevents the P0137 and P0157 Oxygen Sensor Circuit Low Voltage error codes for B1S2 and B2S2);
- Prevents the P0138 and P0158 Oxygen Sensor Circuit High Voltage error codes for B1S2 and B2S2);
- Prevents the P0037 and P0057 Heater Circuit Low error codes (for B1S2 and B2S2);
- Emulates both the signal and the heater circuit of the O2 sensor, so the engine ECU is happy;
- Allows for the complete removal of the post-cat O2 sensor/s and the mounting hole to be used for something else (wideband sensor, flamer kit, etc.).
- Weather resistant aluminum housing enables mounting on the underside of vehicles.
- Swappable wiring with optional plug and play extensions, for installation convenience.
- New universal design with switchable load modes, so the emulator can be fine tuned to the specific vehicle ECUs requirements. Load adjustable between 0.33A and 0.81A.
Easy PnP installation - direct plug-in design with the same plug as the O2 sensor. On vehicles where the plug is on the underside, the weather resistant housing allows direct installation where the plug is, without relocation.
If your car has two downstream O2 sensors after the catalytic converters, you need two emulators.
WARNING: Don't use this emulator on the pre-cat O2 sensors (Bank 1 sensor 1 and Bank 2 sensor 1). They're critical for the engine operation and should always remain operational, in good condition and without any adapters on them. This emulator is only for the Bank 1 Sensor 2 or Bank 2 Sensor 2, AFTER the catalytic converter downstream under the car.
For vehicles which use the downstream sensors for secondary closed loop fueling correction, these emulators may cause a change in the fueling, so we don't recommend using these on such vehicles.

- 1x Rank One Performance O2 sensor emulator with the selected wiring option.
