Aircon Sensorfor A34H0959126A 4H0959126B A/C Pressure Switch Sensor

High Precision High-sensitivity sensing chip accurately tracks refrigerant pressure inside AC lines, sends stable signal to vehicle ECU. It timely adjusts compressor operation, keeps cooling efficiency steady, avoids uneven cold air or intermittent AC shutdown during driving.System Overpressure Automatically triggers protection mechanism under abnormal high/low pressure. Prevent compressor burnout, pipe rupture and refrigerant leakage, effectively extend service life of whole air conditioning system and cut expensive repair costs. Rugged Anti-Corrosion Sealed metal housing with oil-resistant internal structure withstands engine compartment high temperature, moisture, oil splash and vibration. Resist rust and signal drift, maintain stable sensing performance in harsh under-hood environment long-term.OEM Exact Plug Manufactured strictly to original size, thread and plug specs, perfectly matches original mounting position. Directly replace faulty old sensor without threading modification or extra wiring, simple DIY installation to save garage labor fee.
