What Does C0755 Mean?
This code indicates that the Tire Pressure Monitoring System (TPMS) receiver module has detected that one or more tire pressure sensor(s) mounted inside the wheel assembly is not transmitting its radio frequency signal. The body control module or dedicated TPMS module expected to receive periodic pressure and temperature data from all four (or five including spare) wheel sensors but failed to detect a signal from at least one sensor. This prevents the system from monitoring tire pressure for the affected wheel position.
Common Causes
45%
Dead or depleted TPMS sensor battery (sensors have non-replaceable internal batteries with typical 5-10 year lifespan)
30%
Damaged or failed TPMS sensor due to corrosion, impact damage, or internal circuit failure
15%
TPMS sensor not properly programmed or relearned to the vehicle after tire rotation or sensor replacement
10%
Faulty TPMS receiver module or antenna unable to receive sensor signals
Diagnostic Steps
1
Step 1: Use the scan tool TPMS function to identify which specific wheel position sensor is not transmitting (LF, RF, LR, RR, or spare). Note the sensor ID that is missing or showing 'no signal'.
2
Step 2: Perform a visual inspection of the identified wheel, checking the valve stem for physical damage, corrosion, or bent/broken valve stems. Verify tire pressure is adequate (low pressure can prevent some sensors from transmitting).
3
Step 3: Use a TPMS activation tool or low-frequency trigger tool at the suspect wheel to attempt to wake up the sensor and force a transmission. Monitor scan tool for reception of sensor signal and verify sensor ID matches vehicle records.
4
Step 4: If sensor does not respond to activation tool, deflate tire and dismount to physically inspect the TPMS sensor for corrosion, damage, or loose mounting. Check sensor battery voltage if tool capable (typically 2.5-3.0V indicates healthy battery).
5
Step 5: If sensor is damaged or battery depleted, replace the TPMS sensor and perform the manufacturer-specific relearn/programming procedure using scan tool or manual relearn method (drive cycle, stationary, or OBD relearn depending on vehicle).
6
Step 6: Clear codes, test drive vehicle, and verify all TPMS sensors are transmitting properly and code does not return. Confirm TPMS warning light extinguishes and all tire pressures display correctly.

The most common cause of C0755 (Tire Pressure Monitor (TPM) system sensor not transmitting) is: Dead or depleted TPMS sensor battery (sensors have non-replaceable internal batteries with typical 5-10 year lifespan)
Typical repair costs for C0755 range from $75 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive, but you will not receive tire pressure warnings for the affected wheel, which could lead to driving on an underinflated tire and increased risk of tire failure. Repair within a reasonable timeframe and manually check tire pressures regularly until fixed.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C0755 to identify the root cause.
