TIRE PRESSURE SENSOR TIRE 2 VOLTAGE
Tire pressure sensor for tire 2 is reporting an out-of-range voltage.
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 tire pressure sensor for the second tire isn't giving a normal voltage reading, which means it might be malfunctioning or the tire is improperly inflated.
What the computer is actually seeing
The computer expects a voltage between 0.5V and 4.5V from the tire pressure sensor, which changes based on the tire's inflation. A voltage outside of this range triggers the fault.
What a healthy reading looks like
Normal voltage should be between 0.5V (low tire pressure) and 4.5V (high tire pressure).
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. Inspect the tire pressure of tire 2; should be 30-35 PSI for standard tires. Is it within range?
- 22. Check the wiring and connector at the tire pressure sensor for any visible damage or corrosion. Is everything intact?
- 33. Measure the voltage at the tire pressure sensor connector; should be between 0.5V and 4.5V. Does it fall within this range?
- 44. If voltage is out of range, check the wiring back to the ECU. Is there continuity?
- 55. If continuity is good, replace the tire pressure sensor and test again.
Common causes
- Faulty tire pressure sensor for tire 2
- Wiring issue from sensor to the ECU
- Corroded or damaged connectors
- Incorrect tire pressure settings
- Failed ECU processing of sensor data

Frequently asked questions
Is it safe to drive with this code?
It's not immediately dangerous, but it indicates potential tire pressure issues. Check tire pressure soon.
Will this code come back after clearing it?
If the underlying issue isn't fixed (like a faulty sensor or low pressure), the code will likely return.
Why does this code show up alongside other tire pressure codes?
Multiple codes may indicate problems with several sensors or a common wiring issue affecting all sensors.
