Tire Pressure Sensor Fault

Indicates a malfunction in the tire pressure monitoring system (TPMS).

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 sensors in your tires are not working correctly, possibly due to a dead battery, bad wiring, or the sensor itself is faulty.

What the computer is actually seeing

The TPMS control module detects a fault signal from one or more tire pressure sensors that are out of range or not responding. It expects a specific frequency and voltage (typically around 3.0V when active).

What a healthy reading looks like

Each TPMS sensor should send a signal at the rated tire pressure (usually 30-35 PSI) and return a voltage between 2.0V and 3.6V when within normal operating conditions.

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.

  1. 1Check tire pressures manually; ensure they are set between 30-35 PSI based on manufacturer specifications.
  2. 2Inspect the wiring and connectors to the tire pressure sensors for damage or corrosion; repair as needed.
  3. 3Use a scan tool to check for additional TPMS codes that may indicate which sensor is faulty.
  4. 4If a specific sensor is indicated, use the proper diagnostic tool to test or replace the faulty tire pressure sensor.

Common causes

  • Dead TPMS sensor battery (average life of 5-10 years)
  • Faulty wiring or connectors to the sensor
  • Corrosion or damage to the sensor
  • Incorrect tire pressure adjustments or settings

Frequently asked questions

Is it safe to drive with this fault code?

Yes, but maintain proper tire pressure manually and monitor handling, as it may impact safety if tire pressure is insufficient.

Will this code come back after resetting?

If the underlying issue is unresolved, the code will likely return after you reset it and drive a short distance.

Why does this code appear with a C1460 code?

C1450 and C1460 codes often indicate multiple sensors are having issues; resolving one may lead to clearer diagnostics for others.
