C0750

Moderate

Tire Pressure Monitor (TPM) system sensor not transmitting

What Does C0750 Mean?

This code indicates that the Tire Pressure Monitoring System (TPMS) control module has lost communication with one or more tire pressure sensors. The TPMS receiver is not detecting a valid radio frequency signal from at least one wheel-mounted sensor during normal operation. This prevents the system from monitoring tire pressure at one or more wheel positions, disabling the safety function of alerting the driver to low tire pressure conditions.

Common Causes

45%

Dead or weak TPMS sensor battery (sensors typically last 5-10 years)

TPMS Sensor

30%

Physical damage to TPMS sensor from tire service, curb impact, or corrosion

TPMS Sensor
Valve Stem

15%

TPMS sensor not properly programmed or learned to the vehicle after tire rotation or replacement

TPMS Control Module

10%

Faulty TPMS receiver module or antenna interference

Diagnostic Steps

1

Step 1: Using the scan tool TPMS function, identify which specific wheel position sensor is not transmitting by viewing live sensor data or stored sensor IDs. Note which wheel(s) show no signal or missing data.

2

Step 2: Perform a visual inspection of the identified wheel(s), checking tire pressure is adequate (low pressure can prevent transmission), inspect valve stem for physical damage, corrosion, or recent tire service indicators.

3

Step 3: Use a TPMS activation tool to trigger the suspect sensor directly at close range (2-4 inches from valve stem). If sensor responds with a valid signal, check for receiver module issues or relearn requirements.

4

Step 4: If sensor does not respond to activation tool, deflate tire slightly and remove valve core to verify sensor is wheel-mounted type (not valve-stem mounted). Inspect sensor for physical damage, water intrusion, or corrosion.

5

Step 5: If sensor shows no physical damage but won't activate, replace the TPMS sensor and perform complete TPMS relearn procedure per manufacturer specifications using scan tool or manual relearn process.

6

Step 6: After repair, drive vehicle at 20+ mph for 5-10 minutes and verify all four sensors are transmitting properly via scan tool live data and confirm warning light is extinguished.

What causes C0750?

The most common cause of C0750 (Tire Pressure Monitor (TPM) system sensor not transmitting) is: Dead or weak TPMS sensor battery (sensors typically last 5-10 years)

How much does it cost to fix C0750?

Typical repair costs for C0750 range from $75 to $350, depending on the vehicle, location, and whether you do it yourself or go to a shop.

Is it safe to drive with C0750?

Vehicle is safe to drive, but the TPMS safety feature is compromised and will not alert you to low tire pressure conditions. Manually check tire pressures regularly until repaired, as driving on underinflated tires increases risk of blowouts and reduces vehicle handling.

How do I diagnose C0750?

Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C0750 to identify the root cause.
