My TPMS light came on today, but all my tires are perfectly inflated. Should I assume that my 5 year old sensors are coming to the end of battery life?

No but the only way to check the batteries in the TPMS is the A TEQ tool. If a tire shop has a late model TPMS tool or one that has the latest software they may have Fisker listed in the menu

My CSP has new tires for me, so I'll have him check it all while they're off the rims.

First off the the car gets shipped to Florida not Philly its much nicer here Lol .No you didnt damage the sensors actually there isn't anything you could do too damage them.I suggest that you drive the car again check the tire pressure again also the car needs to be driven at least 8 miles without stopping to get the light out. Also the laptop can be sent to you along with the TPMS tool and reset remotely. You would need to walk around the car with the TPMS tool and ping the sensors as the sensors are pinged the horn honks and you move to the next wheel until all four wheels are down.

I would like to rent the laptop and TPMS reset tool from you if it is still available.

Hi Max,

Quick question - what seems to be the issue with your TPMS sensors?

warning light is on

warning light is on

Ahhh - is the diagnostic screen also on? Can you hit the wheel icon to see what sensor is low in air pressure?

The diagnostic screen is inoperative, it displays but will not respond to touch. was told by Joe Ferante it can only be reset with equipment etc.

I find it easier to just change the watch battery inside the TMPS sensor I use the Maxell CR2450HR Battery For TPMS Tire Air Pressure Sensors For PLC. They sell them on Ebay
