Keep the air-fuel feedback loop accurate on your Mazda pickup with the NTK Oxygen Sensor 24012. This upstream, narrow-band sensor is a direct-fit replacement for the 1990-1993 Mazda B2200 (L4-2.2L) and 1989-1993 Mazda B2600 (L4-2.6L). It provides constant closed-loop feedback to the ECU to help control the air-fuel ratio and alert the OBDII system to possible problems with fuel delivery or catalytic converter efficiency.
Switching zirconia design: a narrow-band, unheated 2-wire sensor built to meet or exceed OEM specifications.
Advanced ceramic sensor element: a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat helps protect the element against poisoning.
NTK advantage: a dual-coated platinum interface and thinner ceramic element are designed for fast light-off and quick response times.
Easy installation: comes with OE-specified, water-resistant connector and harness accessory hardware; M18-1.5 threaded mounting with a 7/8 (22mm) wrench size and a 43.75-inch harness.
Extensively tested during manufacturing for quality and reliability. Country of origin: Japan.
It's a direct-fit replacement for the 1990-1993 Mazda B2200 (L4-2.2L) and 1989-1993 Mazda B2600 (L4-2.6L). Check the Buyer's Guide tab to confirm it matches your vehicle.
Is this an upstream sensor?
Yes. This is the upstream oxygen sensor, providing closed-loop feedback to the ECU to help control the air-fuel ratio.
Is this a heated sensor?
No. It's an unheated, narrow-band 2-wire sensor using NTK's switching zirconia technology.
What's included and how does it mount?
It comes with an OE-specified, water-resistant connector and harness accessory hardware. It uses M18-1.5 threads with a 7/8 (22mm) wrench size and a 43.75-inch harness.
What are signs this sensor may need replacing?
Poor fuel efficiency, rough running, or a check-engine light can be signs. These symptoms have other causes too, so diagnose the fault before replacing; if this sensor is the cause, 24012 replaces it.
