2002 Rx300 Fault Code P1125 And Vcs Light On

[Chris CPT]

Hi guys.

My dad recently bought a 2002 RX300. It's a decent one with full service history, and he had the cam belt changed as soon as he bought it.

Whether this issue is to do with that is doubtful, but the other day the engine management light came on, and the VCS (stability control) warning at the same time.

Our local garage checked the engine light with a fault code reader and said it was P11025, which is a throttle body code apparently.

They reset the light but it's come back on again, as has the traction light again.

The car doesn't seem to be driving any differently, but obviously we want to get to the bottom of this.

Any ideas on what it can be guys, and have you and this issue? Could it be related to the cam belt being changed?

Thanks,
Chris

Hi all.

Just to add. The garage that has used a code reader are getting the code P11025, which they reckon is a 'general' code, and not the specific fault. Their machine won't read the individual codes, so it's a diagnostics check required really.

I've searched high and low on the 'net, and cannot find P11025 at all, and the garage insist the code isn't simply P1125 (Throttle Control Motor Circuit Malfunction). The VCS light also came on at the same time too, which is weird.

Thanks,

Chris

Hi Chris, sounds weird as P codes have 4 digits after them, not 5.. Is there a p1025, that it could be?

I bought a mini-VCI cable from eBay last week and have the latest techstream v10 Toyota software and it was a revelation the wealth of info I can now get back as well as change all my c-best settings, code new keys and tweak suspension settings... Not bad for 19quid!
