Frequently Asked Questions about P1535 GMC Code
1. What does the OBDII code P1535 mean on a GMC vehicle?
P1535 indicates an issue with the A/C High Side Temperature Sensor Circuit, which monitors the high-pressure side of the air conditioning system.
2. What are the common symptoms of a P1535 code?
Symptoms may include the A/C not functioning properly, inconsistent cabin cooling, or the A/C system being disabled altogether.
3. What causes the P1535 code to appear?
Common causes include a faulty A/C high side temperature sensor, damaged wiring or connectors, or a malfunction in the A/C control module.
4. Can I still drive my GMC with a P1535 code?
Yes, but the A/C system may not work correctly, and ignoring the issue could lead to further system damage over time.
5. How do I diagnose a P1535 code?
Start by inspecting the A/C high side temperature sensor, checking for damaged wiring or loose connections, and using a scan tool to verify sensor readings.
6. How do I fix the P1535 code on a GMC?
Repairs may involve replacing the faulty A/C high side temperature sensor, repairing damaged wiring, or reprogramming the A/C control module if necessary.
7. Is the P1535 code related to refrigerant levels in the A/C system?
Not directly, but low or high refrigerant levels can stress the system and potentially contribute to sensor issues.
8. How much does it cost to fix a P1535 code?
Costs vary depending on the specific issue, but sensor replacement typically ranges from $100 to $300, including parts and labor.
9. Can a bad A/C high side temperature sensor damage other components?
Yes, if the sensor fails to detect high pressure or temperature accurately, it could prevent the A/C system from shutting down, potentially damaging the compressor or other parts.
10. Will clearing the P1535 code fix the problem?
Clearing the code without addressing the underlying issue will only provide a temporary fix, and the code will likely return.
