I got the engine code P1135 on my Toyota Highlander

Question

My Toyota Highlander check engine light keeps going on and off. When scanned it shows the p1135 code. But at times this code is turned on by itself and after a couple of kilometers it comes up again. Please what can I do to rectify this fault?

Hi there,

This code is an O2 sensor code. The driver side front O2 sensor has a fault. Normally replacing the sensor will resolve the issue.
