Hella 7.05271.52.0 Oxygen Sensor

Oxygen Sensor for Select GM and Isuzu Applications

This Hella oxygen sensor, part number 7.05271.52.0, is a direct-fit emission control sensor for select Pontiac, Chevrolet, Isuzu, and Honda vehicles. It is listed for upstream and downstream positions across multiple OE-number-matched applications, including Pontiac GTO, Chevrolet Aveo, and Isuzu Trooper.

Key Features

• Hella oxygen sensor from the Pierburg distributed by Hella product line
• Part number 7.05271.52.0 for OE-number-matched replacement selection
• Fits upstream and downstream locations depending on vehicle application
• Coverage includes Pontiac GTO, Chevrolet Aveo, Isuzu Trooper, and related models
• Emission control sensor for air-fuel feedback and exhaust monitoring

Detailed Description

The Hella 7.05271.52.0 oxygen sensor is built for specific OE-number-matched applications where accurate exhaust oxygen monitoring is required. Compatible vehicle coverage includes 2004-2006 Pontiac GTO downstream, 2004-2005 Chevrolet Aveo upstream and downstream, 2000-2002 Isuzu Trooper upstream right, upstream left, downstream right, and downstream left, plus additional listed Pontiac, Isuzu, and Honda applications. The Pierburg distributed by Hella line identifies this sensor as part of a focused OE-style replacement range for emission control service.

This part cross-references OE numbers 96394003 and 8972240110 for the same application. Use part number 7.05271.52.0 to verify the correct sensor before ordering, especially on vehicles with multiple sensor locations such as the Isuzu Trooper and Chevrolet Aveo.

What It Is Used For

• Replacing a failed upstream oxygen sensor on a Chevrolet Aveo
• Replacing a downstream oxygen sensor on a Pontiac GTO
• Restoring exhaust feedback on an Isuzu Trooper with OE No. 8972240110
• Addressing check engine light concerns tied to oxygen sensor circuit faults
• Correcting fuel trim and emissions monitoring issues caused by sensor aging

Installation Notes and Tips

Confirm the sensor position, OE number, and connector style against the vehicle before installation. For 2000-2002 Isuzu Trooper applications, this sensor is listed for upstream right, upstream left, downstream right, and downstream left positions. For 2004-2005 Chevrolet Aveo applications, verify whether the vehicle uses the upstream or downstream location. Always inspect the exhaust threads and wiring routing before final tightening.

Quality Assurance

Hella is a recognized OE-focused brand, and the Pierburg distributed by Hella line is cataloged for OE-number-matched replacement use in emission control service.
