What Does P1155 Code Mean?

If your check engine light is on and you’ve pulled a P1155 code, it means that your vehicle’s oxygen sensor heater circuit has malfunctioned. The oxygen sensor heater is responsible for heating the oxygen sensor so that it can accurately measure the amount of oxygen in the exhaust stream. When this circuit fails, it can cause the oxygen sensor to provide inaccurate readings, which can lead to poor engine performance and increased emissions.

In some cases, a P1155 code may also be caused by a faulty oxygen sensor or an exhaust leak.

What is Af Sensor Heater Circuit?

An AF sensor heater circuit is a device that helps to keep the camera’s autofocus system functioning properly in cold weather. The autofocus system in a camera relies on an infrared sensor to detect contrast between objects in the scene and focus accordingly. However, in cold weather conditions, this sensor can become fogged up, making it difficult for the autofocus system to work properly.

A heater circuit helps to prevent this by keeping the sensor warm and free of condensation.
