Walker Products 350-34593 oxygen sensor for the 2006-2015 Mazda MX-5 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. This narrow-band, direct-fit sensor works in the downstream position.
- Monitors the air-fuel ratio to track combustion efficiency
- Made for its specific application and fitment position, with the diagnostic feedback the ECU needs
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 350-34593 oxygen sensor
- Fits: 2006-2015 Mazda MX-5 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can make the engine run poorly, burn more fuel, raise exhaust emissions or turn on the malfunction indicator light, and newer vehicles may store fault codes. Several faults can show up this way, so with the engine off and cool, look over the sensor, its wiring harness and the connector for physical damage before you replace it.
Fits
It fits the 2006-2015 Mazda MX-5 4-cylinder 2.0L and the 2006-2015 Mazda MX-5 Miata 4-cylinder 2.0L as a direct-fit replacement.

Frequently Asked Questions
Does this MX-5 oxygen sensor fit the 2006-2015 Mazda MX-5 Miata 4-cylinder 2.0L?
Yes. Walker Products 350-34593 fits the 2006-2015 Mazda MX-5 Miata 4-cylinder 2.0L and the 2006-2015 Mazda MX-5 4-cylinder 2.0L.
Is the Walker Products oxygen sensor upstream or downstream?
Downstream. Walker Products 350-34593 is a narrow-band, direct-fit sensor made for the downstream position.
What thread size does this narrow-band oxygen sensor have?
The thread is M18 - 1.5, and the sensor has 4 wires.
What can a failing downstream oxygen sensor cause?
It can lead to rough running, higher fuel consumption and exhaust emissions, or a lit malfunction indicator light. A shop can read any stored fault codes.
What is the coating on this oxygen sensor for?
The coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates. The electrodes themselves are a gas-permeable platinum layer.
