I have a 89 toyota cressida, and I got this code 26
Mixture continously rich , I need to change the
ho2s sensor but I don't know where it is located.
Your O2 Sensor is in the exhaust pipe before, or just after the Cat Converter. Look underneath the car for a 1-1/2" tall by 3/4 inch OD sensor with one or two wire comming out of it. Unplug the wires WO Cutting or tearing them. Make sure that they have good contact and continuity from the plug to the other end. Look up the wire loom on-line. Undo the sensor with an adjustable wrench and take it to the NAPA, or any other parts store, who by the way can look up the location of your O2 sensor and tell you how to replace it. They will sell you a new one cheap and you can reverse the procedure to fix it! Good luck.
