P0537

2017-10-10

Description:

  • The fault code P0537 signals that the circuit responsible for the A/C refrigerant pressure sensor is experiencing low input. This could cause the A/C system to perform poorly or not function at all.

Possible Symptoms:

  • A/C system not functioning

  • Poor or inadequate cooling performance

  • Illuminated A/C system warning light

  • Reduced fuel efficiency due to A/C system inefficiency

Possible Causes:

  • Faulty A/C refrigerant pressure sensor

  • Worn or damaged electrical wiring or connections

  • Low refrigerant levels

  • Damaged A/C compressor

Related Parts:

  • A/C Evaporator Temperature Sensor: Prevents the air conditioning refrigerant from becoming too cold. Problems lead to reduced AC cooling

Possible Solutions:

  • Replace faulty A/C refrigerant pressure sensor

  • Repair or replace damaged electrical wiring or connections

  • Recharge refrigerant levels to manufacturer specifications

  • Replace damaged A/C compressor
