2020 Dodge Journey Tire Pressure Monitor Control Module Replacement Cost

Tire pressure monitoring system control module failure, like other electronic components, is random, and predictability is guesswork at best. Failure of the TPMS control module is not as common as replacement of the TPMS sensors because the tire pressure monitoring system sensors are replaced each time the tires are replaced.

When diagnosing the TPMS control module, the technician will simply compare actual conditions to electronic conditions. In other words, If the technician notes that the tire pressure is correct on each wheel but the control module shows incorrect pressure(s), a discrepancy is noted. Discrepancies like this are commonly used as clues which map to the issue. If the technician finds that the issue originates with the control module, whether by physical or scan testing, the module will be verified defective and replaced.

Like any other control module, the location of the tire pressure monitoring system control module (TPMS) will be identified and the technician will then begin removing all obstructing components needed to access and remove the control module. Once accessed and removed, the connectors are cleaned and inspected, and the new module will be installed. After all components are reassembled on the vehicle, the technician will program the TPMS control module and relearn the TPMS sensors. Finally, the technician will test the operation of the system to ensure the customer complaint has been corrected.

Electrical diagnostics in general can be problematic, and there are many variables to account for. When electrical problems arise, diagnostics may take several hours to complete, or just a few minutes. This will significantly impact the cost of repairs. Choosing a facility with proper equipment and training for their staff may significantly reduce diagnostic time needed.

Every possible scenario related to the failure of the TPMS control module can be replicated by one or more failures within the TPMS system. This means that the control module may be blamed for a sensor issue, or a sensor may be blamed for a faulty control module. When the issue has been routed to one circuit, the entire circuit should be tested to prove the diagnosis.

Except for the very advanced DIY mechanic with a strong understanding of computerized circuit diagnostics and testing, this repair should be left to a professional. Diagnostics of electronic systems are difficult for the untrained person to perform correctly. Unless safety and diagnostic methods are understood and followed properly, this should be left to a professional.
