TPMS light on and inaccurate readings on my 2022 Jeep Compass

Vehicle: 2022 Jeep Compass Latitude

Hey forum, I'm having an issue with the Tire Pressure Monitoring System (TPMS) on my 2022 Jeep Compass Latitude. The TPMS warning light has been on for a few weeks now, and the readings for one of my tires are completely inaccurate or just show dashes.

I've checked the tire pressure manually with a reliable gauge, and all tires are at the correct PSI. I've also tried driving for a bit to see if it would reset, but no luck. Could it be a faulty sensor, even on a relatively new vehicle?

Is there a way to reset the system myself, or am I looking at a trip to the dealership? Any insights into common TPMS problems for the Compass would be great!

ClearTheCode admin answer:

TPMS issues, even on newer vehicles like your 2022 Jeep Compass, are not uncommon and typically point to a sensor problem. Here's what you should know and what steps you can take:

  1. Faulty TPMS Sensor:

    • Cause: The most frequent cause of an inaccurate reading or a persistent TPMS light when tire pressure is correct is a failing sensor. Sensors contain a battery that eventually dies, or the sensor itself can be damaged by road debris or during tire service. Even on a 2022 model, a sensor could be faulty from the factory or have sustained damage.
    • Action: A tire shop or dealership can use a specialized TPMS tool to scan each sensor individually. This tool can read the sensor's ID, battery life, and current pressure, helping to identify which specific sensor is faulty. Common OBD-II codes associated with TPMS sensor issues include C1504 (TPMS Sensor Internal Fault), C1501-C1503 (Tire Pressure Sensor 1-3 Fault), or C1505 (Tire Pressure Sensor 4 Fault).

  2. TPMS System Reset:

    • Cause: Sometimes, after a tire rotation or replacement, the system needs to 'relearn' the sensor positions or IDs.
    • Action: While some vehicles have a manual reset button, many modern Jeeps automatically relearn after driving for 10-20 minutes above 15-20 mph. Ensure all tires (including the spare if it has a sensor and is part of the system) are at the recommended pressure. If the light persists, a manual reset using a diagnostic tool might be necessary.

  3. TPMS Module/Receiver Issue:

    • Cause: Less common, but a problem with the TPMS receiver module (which picks up signals from the sensors) or its wiring can also cause system malfunctions.
    • Action: This requires professional diagnosis. A technician can check for communication errors between the sensors and the module, looking for codes like C151D (TPMS Receiver Fault).

When to See a Shop:

  • If the TPMS light remains on after confirming correct tire pressures and driving for an extended period.
  • If you have specific OBD-II codes related to TPMS sensors or the module.
  • If you can't identify the faulty sensor with a basic scanner or if you need a sensor replaced (requires dismounting the tire).
  • It's important to address TPMS warnings, as they are a safety feature designed to alert you to potentially dangerous tire conditions.
