Question type: Maintenance & Repair

Dash insturment reads ac off low refigerant. Compressor is fully charged and works well
if you straight wire it. Is this a bad sensor,if so how Can I determine which one?

1 Answer


the pressure sensors in the air conditioning system are not something you can change at home, the refrigerant in the air conditioning system has to be removed from the system in order to replace the sensor and it is illegal to vent into the atmosphere. take it to an air conditioning specialist to get the sensor replaced. bypassing the sensor could cause a system failure down the road maybe even more expensive than paying to get the sensor replaced.
