The catalyst monitor needs good inputs from both the upstream and downstream O2 sensors to check the operating efficiency. Oxygen sensors are one of the most often replaced sensors. Inputs from the O2 sensors are used by the engine management system to adjust the fuel mixture. This is critical for maintaining low emissions and good fuel economy.
What happens when you replace the knock sensor?
How much power you will lose depends on the octane limit of the engine, and how heavily it relies on the knock sensor input. The vehicles that will lose the most power are high-compression and flex-fuel engines. This is because the loss of power will slow the timing and keep the transmission out of drive until the sensor has been replaced.
