I'd be checking front knuckle wiring wherever it terminates back to the body if it's been apart for axle removal etc.. Ye the engine was out but was fine for ages after that. I have checked much wiring and connections, all seems fine. I have replaced a rear sensor that seemed slightly intermittent, but I am waiting for tyres to get replaced before I can check if this did anything. 12 minutes ago, sidewaysickness said: Honestly I was surprised it had tyre pressure monitoring Me too, although its not really measuring it if it just looks for differences in rotation speed. I would be very surprised if it knew which wheel to control with the abs as well. Altho I guess it can if it can sense individual wheel rotation.

kws Posted July 27, 2022 Share Posted July 27, 2022 If you havent already, try checking the ABS codes and see what comes up https://www.tapatalk.com/groups/ae111_forum/abs-diagnostics-t6366.html Quote Link to comment Share on other sites More sharing options...

ThePog Posted July 28, 2022 Author Share Posted July 28, 2022 Hey @kws@mjrstar So here is the story. I put the new tyres on and went for a drive. It immediately threw an abs light and the tyre pressure light on. So I did the diagnostic thing and it had codes for left rear and right front. Fair enough, I had previously got the abs light when I had not seated the left rear correctly, and like a dick I had forgotten to plug the right front back in. I cleared those codes and the abs light went off. But the fucking tyre pressure one came right back on... So is there a jumper setting to get the tyre pressure fault codes out? I had a look but I can't see anything. I'm tempted to let her loose in it tomorrow and see what happens. Quote Link to comment Share on other sites More sharing options...
mjrstar Posted July 28, 2022 Share Posted July 28, 2022 Probably a dumb question, but have you checked pressures on the newly fitted tyres? Tyre shop will often leave pressure very high when I get tyres done.. They'd need to be within a few psi to keep the system happy. not just flat, for example the system may be unhappy with 2 tyres at 40 psi and the other 2 at 32 psi.

The first thing I did was make sure all the pressures were the same.. Quote Link to comment Share on other sites More sharing options...
xsspeed Posted July 28, 2022 Share Posted July 28, 2022 eh but surely this isnt actively monitoring pressure? that's like mid 2000s tech isnt it? was left rear the problematic one? and did you replace the ABS sensor on that? (sorry not been a long time reader). I had a 97 caldina that had abs fault and turned out to be just the sensor - Zebra replacement had it sorted. Didnt have tire pressure monitoring though Quote Link to comment Share on other sites More sharing options...
xsspeed Posted July 28, 2022 Share Posted July 28, 2022 just caught up - did you actually replace the left rear sensor? Quote Link to comment Share on other sites More sharing options...
ThePog Posted July 28, 2022 Author Share Posted July 28, 2022 Yea I replaced it, the abs is not activating randomly now but it is clearly still reading different wheel speeds. Quote Link to comment Share on other sites More sharing options...
xsspeed Posted July 28, 2022 Share Posted July 28, 2022 Hall effect sensors right? not something weird going on with trigger wheel - i can't picture in my head how they go together right now. can you turn tire pressure monitoring off?

ThePog Posted July 29, 2022 Author Share Posted July 29, 2022 Yea so she took it to school today and it did the ABS overactive fault a couple of times on the way there, but not at all on the way back. I checked the fault codes and there was nothing, however the tyre pressure warning light was flashing its own code. Translating the flashes to the ABS codes it said right front. I cant find anywhere on the net that says the tyre pressure light has its own fault codes, does anyone know? But that was the one I had accidentally left unplugged so maybe it is just that code? Fuck knows. As I am now a certified Toyota tech I decided to check the engine codes while I was there, it had one for the intake air temperature sensor, so maybe I will chuck one of those in as well.

thegreatestben Posted July 29, 2022 Share Posted July 29, 2022 It’s not had a cv or axle change? Different tooth counts on the pulse ring? 1 Quote Link to comment Share on other sites More sharing options...

thegreatestben Posted July 29, 2022 Share Posted July 29, 2022 Also assuming pulse wheel isn’t damaged or slid out of place. Some are a ring that is interference fit. Quote Link to comment Share on other sites More sharing options...
