Bosch 15152 Oxygen Sensor - Downstream or Upstream

Bosch 15152 Oxygen Sensor Overview

Bosch 15152 is a narrow-band heated oxygen sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management across changing engine loads, making it a direct replacement choice for select Cadillac, Chevrolet, Buick, Pontiac, Saturn, and GMC applications.

As part of the Bosch Engineered Oxygen Sensor line, this sensor reflects Bosch’s OE development history in oxygen sensing, including faster closed-loop response from planar narrowband design and durable construction for high-heat, high-vibration environments.

Key Features

• Specific-fit oxygen sensor for direct application matching
• Narrow-band heated design for quicker closed-loop operation
• 4-wire configuration with blade terminals and rectangular male connector
• Threaded mounting with 18 mm thread size and 22 mm hex size
• Metal housing and steel finish for underhood durability
• Wiring harness included with 11.3 in harness length
• Overall length: 15 in; sealing surface to connector end: 13.8 in

Detailed Description

Bosch 15152 is engineered for vehicles that rely on a switching-type upstream or downstream oxygen sensor signal to manage fuel delivery and emissions performance. The sensor uses advanced ceramic elements and optimized heater control to deliver consistent readings as exhaust temperatures change. That makes it a practical replacement for drivers servicing a Chevrolet Malibu upstream oxygen sensor, a Pontiac G6 upstream O2 sensor, or a Cadillac CTS oxygen sensor application where accurate feedback matters.

This Bosch Engineered Oxygen Sensor line is backed by more than five decades of OE development. Bosch’s narrow-band heated design helps the ECU transition into closed-loop operation faster, while the high-temperature-resistant materials are built to handle thermal cycling and vibration. Part number 15152 is also referenced in interchange listings for multiple OE numbers, including 12569429 and 12576131.

What It Helps Address

• Check engine light caused by oxygen sensor signal faults
• Rich or lean fuel trim conditions from inaccurate exhaust feedback
• Slow sensor response during warm-up or closed-loop transition
• Emissions test failures related to upstream or downstream sensor performance
• Rough idle, hesitation, or reduced fuel control precision
