U0430: Invalid Data Received From Tire Pressure Monitor Module

What it means

The Tire Pressure Monitoring Sensor is present on the data bus but the values it reports are implausible — out of range, frozen, or failing the checksum or rolling-count check. The receiving modules reject the data. Tire-pressure readings become unreliable. Causes include a faulty sensor feeding the module, internal computation errors, a software or calibration mismatch after a repair, or bus interference corrupting the frames.

How it works

The tire pressure monitor module collects and reports tire-pressure sensor information over the vehicle network. U0430 is set when another module rejects the TPMS data as implausible; a depleted sensor battery, an incomplete relearn after a wheel change, or gateway routing trouble can cause it.

Common causes

Most likely first.

1. TPMS sensor battery dead
2. TPMS relearn needed after wheel swap
3. Gateway module routing CAN messages incorrectly

Symptoms

• Multiple warning lights may illuminate
• Affected modules may go into limp mode or shut down
• Specific functions inoperative depending on module
• Diagnostic tools may show communication faults

How to diagnose it

1. Scan all modules and review freeze-frame data to find which controller logged U0430 and whether TPMS or network faults are also present.
2. Check each tire's pressure with a gauge and compare it with the vehicle's placard, since readings shown on the display may not be trustworthy.
3. Check whether wheels or TPMS sensors were recently changed and whether the vehicle's required sensor relearn was completed.
4. Use a TPMS-capable scan tool to check each sensor's reported pressure and communication status, noting any missing or implausible sensor data.
5. Inspect the TPMS module, gateway, and accessible wiring, then check CAN routing and confirm sensor compatibility using the manufacturer's information.

Common fixes

• Set tire pressures to the vehicle's specified values and complete the required TPMS relearn if needed.
• Replace a TPMS sensor with a depleted battery or confirmed communication fault.
• Repair damaged wiring or connectors at the TPMS module or gateway.
• Correct gateway routing or replace the TPMS module if testing confirms the module is producing invalid data.

Can I keep driving?

You can usually drive if the tires are correctly inflated, but check pressures manually because the monitor may not warn reliably about a low tire. Avoid long or high-speed trips on a tire with uncertain pressure, and stop if a tire looks damaged or loses pressure.
