GM Genuine Parts 213-4768 (12639692) Heated Oxygen Sensor — for Chevrolet and GMC Models

A check engine light, rough idling, increased fuel consumption, or failed emissions tests — these are common signs that your downstream oxygen sensor needs replacement. The oxygen sensor measures the proportion of oxygen in the exhaust gases and sends this data to the engine control module (ECM). The ECM uses this information to adjust the air/fuel ratio to the optimal value of 14.7:1, optimizing engine performance, emissions, and fuel economy. A faulty sensor can cause poor fuel economy, increased emissions, and potential damage to the catalytic converter.

This is a factory-original GM heated oxygen sensor (OE part number 213-4768 / 12639692), designed for the downstream position on select Chevrolet and GMC models with the 2.4L L4 engine. It features a 4-wire heated design with a triangular female connector and measures 13.75 inches (349.2 mm) in overall length. This is the same part sold at GM dealerships.


When to Replace

• Check engine light (typically P0137, P0138, P0141, or related O2 sensor codes)
• Rough idling or engine hesitation
• Increased fuel consumption
• Failed emissions test
• Poor engine performance
