AC High-Side Temperature Too High (Ford)
What does P1467 mean?
The P1467 code means the vehicle's onboard diagnostic system has detected: AC High-Side Temperature Too High (Ford). This is a moderate severity code.
Common Symptoms
- AC blows warm air during hot weather
- Check Engine Light illuminated
- High-side AC pressure elevated on gauges
- Cooling fans running at maximum speed
- AC compressor shuts down intermittently
Probable Causes (Ranked by Likelihood)
- Restricted airflow through the condenser Very High
- Overcharged refrigerant High
- Condenser cooling fan failure High
- Clogged condenser tubes internally Moderate
- Faulty high-side temperature sensor Low
Step-by-Step Diagnostic Procedure
-
Inspect the condenser for external debris such as leaves, bugs, or mud blocking airflow. Clean thoroughly with low-pressure water.
-
Check that both cooling fans operate and spin at the correct speeds. Use a scan tool to command the fans on.
-
Connect AC gauges and compare readings to specifications. High-side pressure significantly above normal indicates a restriction or overcharge.
-
Recover and weigh the refrigerant charge. Compare to the spec on the underhood label.
-
Test the high-side temperature sensor with a multimeter and compare resistance to the temperature chart in the service manual.
Frequently Asked Questions
Why does my AC only stop working in hot weather?
In high ambient temperatures, the AC system works harder and pressures increase. If the condenser cannot shed enough heat due to debris, fan issues, or overcharge, the system reaches its high-pressure cutoff threshold.
How do I clean the condenser?
Use a garden hose with moderate pressure from the engine side of the condenser (spraying outward). Avoid using a pressure washer as it can bend the delicate fins. Straighten any bent fins with a fin comb.
Can I drive with P1467?
Yes, the vehicle is safe to drive. The AC compressor will shut off to protect itself when pressures are too high. You may not have cold air in hot conditions until the underlying issue is repaired.
