NTK 23553 oxygen sensor for the 1987-1990 Jeep Cherokee 6-cylinder 4.0L and other vehicles measures the oxygen in the exhaust. This upstream NTK oxygen sensor gives the ECU closed-loop feedback to help control the air-fuel ratio.
- Heated narrow-band sensor with a switching titania element
- 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects the element against poisoning
- Dual-coated platinum interface and a thinner ceramic element for fast light off and response
- Built with the latest sensor technology to reduce failures and enhance durability and performance
- Ceramic element controlled from raw material to finished product
Quick facts
- Part: NTK 23553 oxygen sensor
- Fits: 1987-1990 Jeep Cherokee 6-cylinder 4.0L and other vehicles
- Position: Upstream
- Condition: New
A worn sensor can show up as a check engine light, OBDII codes about fuel delivery or catalytic converter efficiency, or poor fuel economy. Before you replace the sensor, rule out exhaust leaks, damaged wiring and fuel-delivery faults, which can light the same warning. This listing is one sensor, and the 1987-1990 Jeep Cherokee 6-cylinder 4.0L takes one.
Fits
The 1987-1990 Jeep Cherokee 6-cylinder 4.0L, the 1988-1989 Eagle Premier 4-cylinder 2.5L and the 1988-1990 Premier V6 3.0L, and the 1987-1990 Jeep Comanche 6-cylinder 4.0L are among the vehicles this oxygen sensor fits, with more beyond them.
