Is It Safe to Drive With a C0750 Code?
Common Symptoms of a C0750 Fault
C0750 Symptoms at a Glance
TPMS warning light on
No pressure reading shown for one tyre
On some vehicles, key fobs may also stop working if a shared receiver module has failed
Possible Causes of C0750
A C0750 code can be triggered by faults across several systems. Identifying the exact root cause requires proper diagnostic equipment and live data — not just reading the code.
Common Causes of C0750
Dead Sensor Battery
The most common cause — these batteries aren't replaceable and the sensor unit is swapped instead.
Sensor Failure
The sensor's internal electronics have failed independently of the battery.
Receiver Module Fault
On some vehicles a shared module reads all sensors and key fobs.
RF Interference
Aftermarket chargers or dash cams can occasionally block the sensor signal.
Why we don't list the exact part: A C0750 code tells you what's happening but not why. Replacing parts without diagnosis is the most common way drivers waste money. A proper diagnosis identifies the specific cause first.

C0750 and Your MOT
If the TPMS warning light is on and the system is confirmed as not functioning correctly, this can result in an MOT failure on vehicles fitted with TPMS from new. Get the sensor diagnosed and, if needed, replaced before booking your test.
