Hi

My tyre pressure warning light came on today, saying the pressure in the right front tyre was low. I checked the pressure and it was only a few psi down, so I pumped the tyre up to 33 and checked the car again but the light was still on? I drove off and went about my business, turning the car off and on a few times and driving at least 30 miles but the light is still on.

I am therefore thinking I have a tyre pressure sensor fault or an abs sensor fault? I had an abs sensor go on my last car and it somehow doesn't feel like that happening on the RRS.

I can't see any signs of a puncture either, which was something else that crossed my mind.

Has anyone else had this issue and what did it turn out to be? or am I doing something wrong? Can it be re set somehow?

Thanks.

May be tps batteries need replaceing

On mine the TPMS warning light doesn't come on till pressure drop to around 25psi as previously let a couple of tyres down to see what it did. Having seen some sensors and not sure you can change a battery in them as they looked sealed in, so think it may be new sensor but not certain on that one. Might be worth checking the aerial/initiator bit wiring etc. inside the wheel arch, also would have thought a faulty sensor would log a fault code so they may need reading.

Cheers

Swap a wheel front to rear or side to side & that will tell You if it’s the sensor or the detector in the arch.you cannot change batteries,it is a full sensor swap & if that’s the case I would get a full set (about £80) if ones gone the rest won’t be far behind. Andy.

Thanks everyone. I found out what it was today....

I noticed that the car was set to 'heavy load' for the tyre pressures, so it was expecting 37/38 psi when I was going to only 33 psi for max four passengers.

I reset the car to 'light load' made sure I was at 33 psi all round and the warning light has gone out.

Simple as that. Feel a bit stupid for not seeing that sooner but at least it means I don't need a trip to the garage.

Would have thought 33psi in the rears is a bit low, personally always run at least 36psi in rears.

Thanks Col I will check my door sticker again and see what it says.

I'm getting this fault showing on the spare. The car is only six months old, & I've checked the spare & it's 40psi, but it warns it's low each time I start the car. current 2015 hse dynamic, grey.

Running 36 on the rears now. Much better Thanks Col
