Product Details

Plymouth Horizon 1983, Oxygen Sensor (234-1002) by Denso®. Position: Upstream. 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.

Specifications:

O2 Sensor Configuration: Direct Fit
Position: Upstream
Sensor Type: Non Heated
Wires Quantity: 1 Wire Lead
Installation Type: Screw
Wire Harness Length: 6.81" (173 mm)

Features:

  • Corrosion-resistant stainless steel construction
  • PTFE filter blocks efficiency-robbing contaminants
  • Refined zirconia element improves sensor response
  • Superior design maximizes engine performance and fuel efficiency while reducing fuel consumption and harmful emissions
  • Ensures smog test compliance

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 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, 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.

Denso® factories are QS9000 and ISO9000 certified worldwide, just one of the many reasons why zero defects for parts produced in the millions is a reality for DENSO. A recipient of the prestigious Deming Award for quality in 1961, Denso spent over five decades perfecting technology and processes, a claim that few automotive manufacturers can make. Denso First Time Fit™ products — including A/C compressors, starters, alternators, oxygen sensors, ignition wire sets, fuel pumps, cabin air, oil and air filters, wiper blades and more — are products built and tested to OE-standard offered for the aftermarket by DENSO. Each of these products is precision-built for exact replacement so you don't have to worry about doing the same job twice.
