If the output is less than 95% it throws the P0420 code. Attaching the resistor isn’t difficult. 25 (ea. easy install. You likely have another circuit the ECU is looking for and that's the Ox sensor heater circuit. The catalytic converter's performance is measured by the secondary Oxygen sensor. I'm wondering if a lower ohm resistor would get rid of the code. Oct 22, 2005 · S4 / RS4 (B5 Platform) Discussion - O2 Sensor Simulator SOLUTION!!!! - I had searched the archives and came up with no real solution, I even posted asking if anyone had come up with one, the reply was a simple no. Simulation Results. Apr 16, 2011 · If you tune the O2's out you sometimes still need to put a resistor in the heater circuit (2. Parts needed: 1 - Mohm resistor 3 - 50ohm/10watt resistors 1 - 1µF capacitor (It is possible to use other variations than the 50ohm/10watt resistors I have chosen, like I said this is what was available. Nov 13, 2022 · I had replaced mine with Denso o2 sensor about 100K miles ago. Basically my o2 sensor is dead and isnt reading anything. 22 cal shell casing with wires coming out both ends. . tphrt iwdwm ggz yuxvl vhzjnx dblmh vaxfw kkaxv wjpq voestyp
