U0330 code meaning
Software Incompatibility With Tire Pressure Monitor Module
What U0330 means
The tire pressure monitor module receives the radio messages of the wheel sensors, evaluates the pressures and, on many systems, works out which sensor sits on which wheel; from this it drives the warning lamp and cluster messages. U0330 is set when a partner controller finds the software or variant of this module unsuitable, usually after a replacement or a partial update. No manufacturer documents U0330 publicly. Porsche shows how much depends on that software: on Panamera and Cayenne from 2017, version 0630 could raise a TPM fault message for no reason, and the unit had to be reprogrammed and coded (90/18). FCA reflashed the TPM software of 2014–2015 Journey, Durango, Charger and Grand Cherokee when sensor location codes C151D and C1581 appeared (08-024-15). U0127 is lost contact. Only the tire warning is affected.
U0330 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.3 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0330
- Tire pressure warning lamp or TPMS fault message in the cluster
- Tire pressures not shown or shown on the wrong wheel
- Code appears after work on the TPMS module or a software update
Common causes of U0330
- Most likelyTPMS module replaced or taken from another vehicle without programming and coding
- PossibleModule still on a software level that the partner controllers no longer accept
- Less likelyModule configured for another wheel, tire or sensor variant
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0330 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 30 | The exact fault in that area. |
What to do next
- Note U0330 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0330
What does U0330 mean?
U0330 means "Software Incompatibility With Tire Pressure Monitor Module". The tire pressure monitor module receives the radio messages of the wheel sensors, evaluates the pressures and, on many systems, works out which sensor sits on which wheel; from this it drives the warning lamp and cluster messages. It is a generic code, so it means the same on every make.
Is it safe to drive with U0330?
U0330 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0330 fail an emissions test?
U0330 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0330 to fix?
Difficulty: workshop only. A typical repair takes 0.3 to 1.5 hours of work. This is a job for a workshop.
Will U0330 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
