Review on Denso 234-9025 Air Fuel Ratio Sensor: Precision Measuring for Optimal Combustion by Fort Steffen

My 99 Honda Accord LX Check Engine Light came on at 45,000 miles. Read it with my ODBII reader and it came back P1164 - Primary O2 sensor (upstream, pre-cat). I cleared it with my OBDII reader and the CEL was gone but the C (Catalyst Monitor) icon on the OBDII reader kept flashing after driving the car a few miles and DTC P1164 came back last week. I bought this sensor, installed it myself and voila! The trip computer reset everything and the green light on my OBDII reader came on. Saved me a bunch of bucks and thanks to other reviewers for suggesting this sensor is a suitable replacement part for ULEV 99 Honda Accord - California engines. Don't settle for cheap sensors and get your car fixed the first time by buying the right one, although it costs over $100 but still cheaper than other online retailers, dealerships and auto parts stores plus labor costs.
