• Description:

  This genuine Motorcraft heated exhaust gas oxygen sensor is the downstream/rear catalyst-monitor unit for older Ford gas trucks and vans. Mounted after the catalytic converter, it reports exhaust oxygen content to the powertrain control module so the system can confirm the converter is working and complete its emissions readiness monitors. Motorcraft catalogs it as a rear/lower Oxygen Sensor, and it interchanges with Ford service number GU2Z-9G444-A. Verified fitment covers roughly 1997-2007 Ford applications, including F-150 in the 1997-2003 range and the 2004 Heritage, Super Duty trucks, and related light- and heavy-duty gas models of the era. A failing downstream sensor typically sets a check engine light with catalyst-efficiency or oxygen-sensor circuit codes, causes failed emissions or readiness testing, and can lead to reduced fuel economy or hesitation as the module loses accurate feedback. Age, heat cycling, and contamination from oil or coolant all shorten sensor life. Install the correct Motorcraft replacement to restore proper monitoring, apply anti-seize to the threads only, torque to specification, and keep the harness away from the exhaust. The exact Motorcraft sensor ensures correct connector, wire count, and calibrated response.

• Applications: 1997-99 LD. 1999-07 SUPER DUTY. 1992-96, 1997-98 HD. F150 1997-03, HERITAGE 2004.
