Doosan A343016 OXYGEN SENSOR for G15/18S2 Forklifts

Overview

The A343016 OXYGEN SENSOR is a replacement oxygen sensor designed for Doosan LPG-powered forklifts, including the G15/18S2 and related G-series models. The oxygen sensor continuously measures the amount of oxygen in the exhaust stream and sends this data to the engine control unit, which uses it to fine-tune the air-fuel mixture. A worn or faulty sensor can cause rough idling, higher fuel consumption, sluggish acceleration and stored fault codes — problems that directly affect productivity and operating costs. Replacing it with the A343016 helps restore accurate fuel metering, smoother engine performance and cleaner exhaust output on compatible Doosan trucks.

Compatibility

The A343016 for G15/18S2 and other listed models fits the following Doosan forklift series:

• G15/18S2
• G20SC-2 series, including SB1018 and SB1070 (F.C.U.) configurations
• G20/25/30/32/33P-3 series, including SB1074 (F.C.U.) and SB1012-01 (G430/G430E) variants
• G20/25/30/32E-3 series

Fitment can vary with engine and serial number, so we recommend checking the model and serial plate on your truck before ordering. If you are unsure whether the A343016 OXYGEN SENSOR matches your machine, our support team can help verify compatibility using the details from your forklift’s data plate.

Quality and Reliability

This oxygen sensor is produced to match Doosan’s original specifications for thread size, connector type, sensing-element response and operating temperature range. Consistent signal output is especially important on LPG engines, where an incorrect air-fuel ratio quickly shows up as hesitation, hard starting and excessive fuel use. Choosing a sensor built for these G-series engines supports a direct fit without modifications and dependable long-term feedback to the engine control unit.

Installation and Maintenance Tips

• Work on a cool engine and disconnect the battery before starting.
• Unplug the sensor connector carefully rather than pulling on the wiring.
• Apply anti-seize compound to the threads if the new sensor is not pre-coated, keeping it away from the sensor tip.
• Tighten to the manufacturer’s specified torque and avoid over-tightening.
• Route the harness away from hot exhaust components and secure it clear of moving parts.
• Clear stored fault codes after installation and re-check engine behavior under load.
• Inspect the sensor periodically; LPG engines can foul oxygen sensors over time, particularly with oil consumption or contaminated fuel.
