Product Details

Part Number: 234-9064
UPC: 42511115200
Manufacturer: Denso
O2 Sensor: Primary

This Denso primary O2 sensor is a direct replacement for Acura/Honda parts 36531-PRB-A11, 36531-PZD-A01, and 36531-PPA-003. This is a direct plug and play sensor, so wiring or cutting is required.

Denso Description

DENSO's light duty oxygen sensor started to appear on vehicles with the development of fuel injection systems. The basic job of the sensor is to monitor the air fuel mixture under idle, moderate acceleration and cruise conditions. Under heavy acceleration the oxygen sensor goes into "open loop," which basically means that the engine management computer system ignores the oxygen sensor. Oxygen sensors have a smaller range of limits in detecting and adjusting the difference from an optimum air/fuel ratio.

As the automotive industry continues to improve on their standards DENSO is keeping the pace with advancements in our engineering to meet the demands from the industry. Also, as car owners are holding on to their vehicles for longer periods, DENSO continues to make auto parts available for those critical replacement parts for all applications.

Oxygen Sensors

Oxygen sensors, also known as Lambda sensors or O2 sensors among some vehicle manufacturers, are among the most sensitive and critical components on your car's engine. Earlier fuel injection systems employed one oxygen sensor in the exhaust system to maintain closed-loop air/fuel mixture control. However, today's engines may use as many as four sensors, which monitor not only exhaust gas oxygen content but catalytic converter efficiency as well. In order to perform these functions properly, the sensors must adhere to OE standards within incredibly close tolerances. A malfunctioning or incorrectly calibrated oxygen sensor can hurt driveability and illuminate the malfunction indicator, resulting in costly and time-consuming repairs. DENSO First Time Fit® oxygen sensors are designed to meet those tolerances and more. The DENSO oxygen sensor catalog offers one of the most complete product lines in the industry, from Acura to Volvo.

Nathan Matutinovich | April 16th, 2016

Great product!
Danny Quach | February 16th, 2016
Finally got around to replacing my old o2 sensor that's been burnt out for like 3 years. This new one from Denso fits perfectly and looks like the oem deal. After i replaced it, my check engine light went away! :D It's definitely a cheaper alternative for oem. Would recommend to all my RSX fellas who need their primary o2 sensor replaced.
Customer services

I purchased this Denso O2 sensor, which worked great, but the customer service by Chris was by far the best even through online chat. Came for the product but made a friend! Thx again Chris and Kseries.
Just like OEM
IronGumby | June 16th, 2014
Looked exactly like the one I pulled out with a bad heater circuit. CEL went away after two days. Even has threads pre-coated with anti-seize!
This is the oem one.
wayne woo | May 31st, 2013
Same as oem that I pulled from front of cat (toward engine). Fixed my CEL 41.
