Default P0141 and P325 on Quest Year 2000

My 2000 Nissan Quest has the following diagnostic codes,
1. Emissions-Related Powertrain DTCs, Mode3:
Electronic Control Unit ID: 10
P0325, Knock Sensor 1 Circuit Malfunction (Bank 1 or Single Sensor )
P0141, O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
2. Continuously Monitored Systems DTCs, Mode 7:
Electronic Control Unit ID: 10
P0325, Knock Sensor 1 Circuit Malfunction (Bank 1or Single Sensor)

Anyone has similar problem? What is the actually problem? I heard that it is likely the O2 sensor problem and the knock sensor error will go away once the O2 sensor if fixed. Any suggestions?

The problem is most likely a bad Rear O2 sensor and knock sensor. Before replacing the sensor you should always check the connectors and fuses for the sensors. If al the wires are OK, you should replaced the O2 sensor first and erase the codes, it is possible that the knock sensor code was triggered by the O2 sensor. You can learn more about the sensor and wire diagram in the "Engine Control" section of the service manual, you can download the section free from here: Knowledgebase - 2000 Quest - Nissanhelp.com

I have a 2002 Quest with 0141 and 325 also. I've had the O2 Bank 1 Sensor 2 replaced. Codes erased and the light came back on in 2 miles. The shop said knock sensor, 5.5 hours of labor! This vehicle is running perfect and getting good gas mileage. The manual says a knock sensor won't turn on the service engine light. Very frustrating as the inspection program in Illinois won't even test the vehicle with the light on. The inspection is a load of crap because only vehicles NEWER than 1995 are being tested.?!
