The factors influencing the cost of diagnosing and fixing the automobile fault code p1532 include the estimated repair time of 1.0 hour.

Most auto repair shops typically charge between $75 and $150 per hour for their services. These factors contribute to the overall cost of resolving the fault code.

The P1532 fault code refers to a problem with the AC Evaporator Temperature Sensor Circuit.

This sensor is monitored by the HVAC Control Module, which keeps track of the temperature of the evaporator. When the air is cold, the sensor’s resistance and signal voltage are high. Conversely, when the air is warm, the resistance and signal are low.

In the case of the P1532 code, the issue lies with the circuit having a low voltage. This means that the sensor is not providing the expected signal to the HVAC Control Module, indicating a potential problem with the AC system’s temperature regulation. It is important to address this issue promptly to ensure proper functioning of the heating, ventilation, and air conditioning system in your vehicle.

What are the possible causes for the automobile fault code p1532?

If you see the engine light or service engine soon warning light on, the fault code P1532 could be the culprit. This code is often caused by a faulty A/C Evaporator Temperature Sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix the issue, visually inspect the wiring harness and connectors, checking for any damage or corrosion. Also, be sure to look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, start by checking the possible causes. One of them could be a faulty A/C Evaporator Temperature Sensor or an open or shorted harness or a poor electrical connection in the sensor circuit. To visually inspect the problem, examine the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors.

What should I look for specifically when checking for damaged components or corroded connector pins?

When troubleshooting an engine light or service engine soon warning light, it’s important to check for damaged components and corroded connector pins. These issues can cause faults in the A/C Evaporator Temperature Sensor, leading to the light being triggered. To fix this, visually inspect the wiring harness and connectors, paying close attention to any signs of damage or corrosion. Look for broken, bent, pushed out, or corroded pins on the connectors. This thorough inspection will help identify and resolve the issue effectively.
