TPMS Diagnostic Information – Honda Fit, 2008-2020
Over the next couple of months, we will be reviewing the best-selling Cars, SUVs, Minivans, and Trucks of 2019. During the month of March, we will focus on the best-selling cars in 2019 in the United States.
After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems.
The Honda Fit is manufactured with an indirect and a direct TPMS system, depending on the year. Direct TPMS has TPMS sensors installed in the wheel; if one or more tires indicate low tire pressure, the TPMS sensors will transfer the information to the vehicle’s ECU. An indicator light (low-line TPMS system) or each tire pressure will show on the dash (high-line TPMS system). The indirect TPMS system does not have TPMS sensors in the wheel; TPMS is measured by wheel speed through the ABS system.

The Honda Fit direct TPMS OBD relearn is unique compared to other OBD relearns. When activating sensors, start with the left front sensor, then go counter-clockwise. The order is left front, left rear, right rear and right front sensor during the TPMS activation process.
As cited in the TIA TPMS relearn chart, for Direct TPMS Honda systems 2008-2012, “a properly formatted TPMS scan tool is required to learn new sensor IDs when replacing sensors. After sensor ID’s are registered to the vehicle, the [TPMS] MIL (malfunction indicator light) will flash until the vehicle is driven and the sensor ID’s are received by the vehicle. This process can take 1-10 miles of continuous driving.”
For direct TPMS systems on the Honda Fit for years 2008-2014, a TPMS relearn is recommended when replacing a sensor. However, for indirect TPMS systems on the Honda Civic for years 2014-2020, a TPMS re-calibration is recommended when changing air pressure, rotating tires and replacing a tire or TPMS sensor.
Use the VT56 to retrieve Honda TPMS DTC codes by selecting the “Service” icon. After selecting the Make, Model, and Year, select the DTC code icon. Use the OBDII module to retrieve the Honda DTC TPMS information to diagnose and service the TPMS issues determined.
