Hello and welcome. My name is ***** ***** you for visiting the site, I will be happy to assist you today.
The PCM has the capability to monitor this process by using a rear Heated Oxygen Sensor (HO2S 2) . The HO2S 2 is located in the exhaust stream past the catalytic converter. The sensor produces an output signal which indicates the storage capacity of the catalyst.
This in turn indicates the catalyst's ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S 2 signal will be far less active than the signal produced by the front Oxygen Sensor (O2S 1) .
Most times it is just the sensor but I could get you the test if you like.
