Tire Pressure Sensor Circuit Malfunction
There’s a problem with the tire pressure monitoring system's sensor circuit.
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 is either not working or has lost communication with the vehicle's computer, which means it can’t tell if your tires are properly inflated or not.
What the computer is actually seeing
The vehicle’s computer expects to see a voltage or signal response from the TPMS sensor. If it doesn't, or if the response is outside normal parameters, it triggers the code.
What a healthy reading looks like
The sensor should typically provide a voltage signal around 0.5 to 3.0 volts representing different tire pressures; if the signal is below 0.4V or above 3.1V, it's considered faulty.
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.
- 1Check tire pressures on all tires, ensuring they are within specification (usually 30-35 PSI).
- 2Inspect wiring and connectors going to the TPMS sensor for wear, damage, or corrosion.
- 3Test the tire pressure sensor output using a multimeter; it should be within the expected voltage range (0.5 to 3.0 volts).
- 4If the sensor is faulty, replace it and reset the TPMS system. Ensure each sensor is programmed to the vehicle. If the issue persists, check for programming errors.
Common causes
- Faulty tire pressure sensor
- Bad wiring or connectors
- Dead battery in the sensor
- Interference from aftermarket equipment
- Improper tire pressure

Frequently asked questions
Is it safe to drive with this code?
Yes, but you won't have accurate tire pressure readings, which can lead to unsafe tire conditions.
Will this code come back after clearing it?
If the underlying issue isn't resolved (like a bad sensor or wiring issue), it will likely return.
Does this code indicate a problem with all tires?
Not necessarily. It could be one faulty sensor, but you should check all tires to be sure.
