Ranger TPMS Fault

Ranger owners, I have a 2001 Ford Ranger with a gasoline engine, 124208 km on the clock. I'm getting a persistent 'Tire Pressure Too Low' warning, even though the tire pressures are fine. The error shows in the speedometer and is stored in the error memory. Could this be a faulty sensor with a dead battery? I've checked for leaks. Any ideas before I face big repair costs?

Hey, I've got a Ranger too, and this sounds familiar! I had the same 'Tire Pressure Too Low' warning and dash light. The TPMS sensor battery is likely dead; they usually fail after a while. Before replacing anything, check the tires at different temperatures. Sometimes, a slight temperature drop can trigger the system. TPMS alerts you when a tire is significantly underinflated, like 25% below the recommended pressure.

That's interesting! When you say 'similar symptoms', did the error code consistently appear in the error memory? How old was your Ranger when this happened? I'm trying to see if my sensors are the same age as yours. If it's a temperature drop, would the light go off when the tires warm up, or would it need a reset?

Yep, the error code was always there until I fixed it. My Ranger was about the same age as yours, maybe newer. The light might go off temporarily if it warmed up, but the problem remained. I took it to a workshop after checking everything. They said it was a sensor battery and replacing it fixed everything. It saved me a lot of trouble trying to figure it out.

Thanks for sharing! Your advice and the similar symptoms make me think I should schedule a workshop appointment to check the TPMS sensors. Knowing a sensor replacement could fix it is good, and I'll be ready for the potential 280€ repair cost. I appreciate your help!
