Hello,

The vehicle hesitates sometimes, scanning the vehicle. The codes display is shown on the image below, I cleared the codes but when the engine is started and scanned again it was only the code P1135 displayed on the scanner. Is it that the sensor is bad?
How can it be tested?

Hi,

The codes appear to be related and specific to the air/fuel sensor heated circuit.

If you look below, I attached the description and the diagnostics related to the P1135. Take a look through them and let me know if they help.

Take care,

Joe
