• Specific-fit design for the listed vehicle applications
• Threaded mounting type with 18.0 mm thread diameter
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for application-specific fitment
• Wiring harness length: 21.97 in.; overall length: 25.51 in.

Application Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered for OE-style replacement use. Part number 350-34595 is built for downstream placement and is listed for 1993-1996 Mitsubishi Mirage and 1993-1995 Dodge Colt models in the exact emissions and sensor positions shown below. If you are replacing a downstream oxygen sensor on a Mitsubishi Mirage or Dodge Colt, this part number is matched to the ECU feedback requirements for those applications.

This part cross-references no additional part numbers in the provided data.

What This Sensor Helps Address

• Check engine light related to downstream oxygen sensor faults
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel correction
• Higher exhaust emissions from a failing heated oxygen sensor
• Stored ECU fault codes tied to the affected sensor circuit

Fitment

• Fits 1995-1996 Mitsubishi Mirage, downstream oxygen sensor for B1S2, not for vehicles in California.
• Fits 1995-1996 Mitsubishi Mirage, downstream Bank 1 Sensor 2 for Non-Calif-ESV vehicles.
• Fits 1995-1996 Mitsubishi Mirage, downstream oxygen sensor for second bank, sensor 1, non-California emissions.
• Fits 1995 Dodge Colt, downstream OE replacement.
• Fits 1993-1994 Dodge Colt, downstream oxygen sensor for B1S2 position in California emissions.
• Fits 1993-1994 Dodge Colt, downstream oxygen sensor compatible with California-ESV vehicles in bank 1 position 2.
• Fits 1994 Mitsubishi Mirage, downstream fits downstream bank 1 sensor 2 on specific vehicle models.
• Fits 1993 Mitsubishi Mirage, downstream oxygen sensor for B1S2 position in California emissions.
• Fits 1993 Mitsubishi Mirage, downstream oxygen sensor compatible with California-ESV vehicles in bank 1 position 2.

Installation Notes

Confirm the sensor position, emissions package, connector shape, and thread size before installation. Inspect the sensor wiring harness and connector for damage, since damaged wiring can shorten sensor life and affect ECU feedback. Verify the downstream location on the vehicle and compare the existing connector and harness length to the replacement part before installation.
