Power Steering Pressure Sensor Circuit Range / Performance Problem
The power steering pressure sensor is reporting out-of-range values.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The power steering pressure sensor measures the amount of pressure in the power steering system. If it sees numbers that are too high or too low compared to expected values, it throws a code saying there's a problem.
What the computer is actually seeing
The computer monitors the voltage output (usually between 0.5V to 4.5V) from the power steering pressure sensor; out-of-range values trigger a fault.
What a healthy reading looks like
Pressure sensor should output a voltage of 1.0V (at low pressure) to 3.0V (at high pressure) under normal conditions; anything outside this typically prompts the C1325 code.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check power steering fluid level; ensure it is at the recommended level and proper type.
- 22. Inspect the wiring and connector for the power steering pressure sensor; look for damage, corrosion, or loose connections. Repair as necessary.
- 33. Use a scan tool to monitor the voltage output of the power steering pressure sensor while turning the steering wheel; verify it operates within expected range.
- 44. If voltage is out of range, replace the power steering pressure sensor and recheck system operation.
- 55. If voltage is normal, check for hydraulic issues in the power steering pump or system.
Common causes
- Faulty power steering pressure sensor
- Wiring issues or shorts in the harness
- Power steering fluid leaks leading to pressure drops
- Incorrect power steering fluid level or type
Typical repair cost
$$ - $$$

Frequently asked questions
Is it safe to drive with code C1325?
Yes, but you may experience steering difficulty. Repair soon as it can lead to more issues.
Will the code come back if I clear it?
If the issue isn't fixed, the code will likely return after some driving.
Why does this code appear alongside other power steering codes?
Many power steering faults can affect the sensor's readings, causing multiple related codes to trigger.
