• Overall length: 26.1 in.

Detailed Description

Walker Products 350-34327 is part of the Walker Products Aftermarket engine management line, which focuses on OE-style replacement sensors for vehicle-specific applications. This oxygen sensor is built for downstream bank 1 sensor 2 placement on 1996-1998 Suzuki Sidekick models, helping the engine control system monitor exhaust conditions and maintain accurate feedback to the ECU. The heated design supports quicker sensor activity after startup, while the specific-fit construction helps match the original application requirements. If your Suzuki Sidekick is showing fuel trim issues or emissions-related fault codes, 350-34327 is the correct replacement to verify against the original sensor location and connector style.

This part cross-references Walker Products 350-34327 for the same application.

What It Helps Address

• Check engine light related to downstream oxygen sensor performance
• Incorrect air-fuel feedback to the ECU
• Reduced fuel economy caused by a failing sensor
• Elevated exhaust emissions
• Poor engine operation tied to sensor signal loss

Installation Notes and Tips

Confirm the original sensor position before installation: this part is for downstream bank 1 sensor 2 use on select Suzuki Sidekick models. Inspect the wiring harness and connector for heat damage, corrosion, or abrasion before replacing the sensor. Verify thread size, connector shape, and wire count against the removed unit to ensure proper fitment. Clear stored fault codes after installation and confirm the repair with a scan tool if the vehicle previously logged emissions-related codes.
