Product Details

The J.C. Whitney JARBM960913 is a direct-fit OEM replacement heated oxygen sensor designed for the downstream front position. Built to restore proper exhaust gas monitoring and fuel trim feedback, this sensor helps maintain optimal engine efficiency and emissions compliance.

This is a 4-wire heated (HO2S) sensor, meaning it includes an internal heating element that brings the sensor up to operating temperature quickly — improving accuracy during cold starts and reducing harmful emissions during engine warm-up. The downstream (post-catalytic converter) location allows the engine control module (ECM) to monitor catalytic converter efficiency and adjust fuel delivery accordingly.

Key Features:

  • Direct OEM Replacement — engineered to match the original sensor's fit, form, and function
  • 4-Wire Heated Design — integrated heater circuit for fast activation and consistent signal output
  • Downstream Front Position — monitors catalytic converter output for precise ECM feedback
  • Plug-and-Play Installation — uses the factory wiring connector for a hassle-free swap
  • Helps Resolve Diagnostic Trouble Codes — addresses common O2 sensor-related DTCs such as P0136, P0141, and related codes
  • Restores Fuel Efficiency and Emissions Performance — a failing downstream sensor can cause rich/lean conditions and failed emissions tests

The J.C. Whitney JARBM960913 oxygen sensor is manufactured to meet or exceed OEM specifications, making it a reliable, cost-effective solution for restoring your vehicle's exhaust monitoring system to factory performance.

Easy to oreder - an excellent price.

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Super smooth transaction, and fast delivery. Just waiting for my mechanic to open packages and verify all correct parts, but I don't expect any issues. Would definitely purchase and recommend others do business with Motorsport.com again

No issues

Great service and product!

Your selection and service is great. The only issue i had was knowing if the product i was ordering was a stock item. I had to contact your customer service about three days after ordering to get an estimated delivery time, would have been nice to know sooner.
