B2606 – OBD-II DTC

OBD-II DTC B2606 – A/C Temperature Sensor Out of Range

DTC B2606 meaning

DTC B2606 refers to a diagnostic trouble code indicating that the A/C temperature sensor is out of range. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s systems. The A/C temperature sensor is responsible for measuring the temperature of the air entering the vehicle’s air conditioning system. When the readings from this sensor fall outside the expected range, the vehicle’s computer triggers this code to alert the technician of a potential issue.

DTC B2606 symptoms

Common symptoms associated with DTC B2606 may include:

• Inconsistent or incorrect A/C temperature output
• Air conditioning system not functioning properly
• Increased cabin temperature
• Possible activation of the check engine light

DTC B2606 causes

Several factors can lead to the triggering of DTC B2606, including:

• Faulty A/C temperature sensor
• Wiring issues, such as damaged or corroded connectors
• Short circuits or open circuits in the sensor circuit
• Faulty engine control module (ECM) or software issues

DTC B2606 seriousness

The seriousness of DTC B2606 can vary depending on the symptoms experienced. While it may not pose an immediate safety risk, it can lead to:

• Reduced comfort due to ineffective air conditioning
