1999 Kia Sportage Repair Question
Kia Sportage Sensor Problem
Diagnostic fault codes never say to replace parts. They only indicate the circuit or system that needs further diagnosis. You could have a wiring problem to the sensor, a leak in the fresh air tube between the sensor and throttle body, or the sensor could be defective. There's a procedure for checking the wiring to eliminate that first, THEN you can suspect the sensor.
