TPMS light
« on: August 06, 2024, 06:28:12 PM »
Hi all

I went with my sister-in-law to find her her first car in 14 years and with a very specific set of requirements, we found a lovely 64 plate Honda Jazz.

When we did the test drive I saw the light and mentioned it to be fixed.

When we picked it up, the light was off, we got 10 minutes down the road and it turned on again.

She called up the garage and they said bring it back.

I brought it to them today and I just had a call saying they read the codes, did a reset and now all we have to do is drive it a few miles for the system to recalibrate.

I've done some Googling and reading a lot on this forum and saw a post about if the TPMS symbol has a cross through it, then there's a bigger issue.

I've attached a photo of it.

Does what the garage say sound right? They're not a main dealer, just a second hand car forecourt ... It doesn't sit right with me their solution, but if it sounds plausible to anyone here I'll give it a go! Just don't fancy driving back and forth again as it's about 30 miles away.

Cheers !

Well we took the car back and they said 2/4 wheels had sensors missing... I don't really think this model was meant to have them as I can't really find them, but we live and learn.

Does this sound right?

I do not think there are sensors within the wheels. It is based on rotation speed of the wheels, calculated using the antilock brake sensor outputs.

It might be the system cannot calibrate due to a sensor malfunction, but then there needs to be a fault in the antilock brake system as well?

Another thing I can think of: I heard of a case in which 1 tyre was replaced because of a puncture. The difference in circumference between the left and right front tyre was too much for the system to calibrate and it kept throwing errors. Also, as this was a hybrid, it would not reduce the engine revs as it normally would, because the computer decided the car was doing corners all the time. It took 2 months and a Japanese engineer to find out the slightly larger (less wear) tyre caused it all.

Good luck!

The MK2 Jazz should have TPMS sensors in the wheels. If like mine, they have metal valve stems as opposed to rubber stems.

First off check the car wheels the tyre valves ought to be smaller sized silver coloured NOT the usual black rubber tyre valves.
Resetting or clearing an electical fault is NOT a fix ask the garage to ID  the fault then rectify with new part .

The Honda TPMS  part 42753 TLO G520 are not cheap even the aftermarket VDO unit part number  S180052059Z  are questionable quality and around £50 each . You may find poor quality Chinese made copy parts dont bother.

As regards the reset by the garage the Honda will recognize the TPMS signal within 30 seconds of being fitted and working correctly. The opposite of when you swop over a set of wheels without TPMS you can drive 3 miles or so before not working signal is recognized and warning light displayed on dash.
