Q: 2009 ford escape tire pressure sensor fault

First, be sure that the alert you are seeing is not due to actual low tire pressure. Using a tire pressure gauge, if you do find low pressure in one or more tires, add air but you should also consider the possibility that there is a leak. If tire pressure at all 4 tires is within spec you may have a problem in the TPMS (tire pressure monitoring system). Inasmuch as TPMS is an essential and very useful safety feature, you should definitely have the TPMS repaired if there is a problem. If you desire that this problem be diagnosed by a certified Mechanic, dispatched by YourMechanic right to your location, please request a TPMS warning light diagnostic and the responding certified mechanic will get this resolved for you. Typically, if there is a TPMS system fault, there will be trouble codes that the mechanic will be able to download and those codes will inform and speed the diagnostic. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
