1KZTE Overboost?

[Harveyp]

Hi there everyone.
I have recently installed a boost gauge in my 1998 Hilux Surf Limited due to the fact I have felt a loss of power. I notice the boost gauge will shoot up to 15psi full boost, then drop back to 11psi and flatten out. Is this a sign of over boost?

To add to that, I just did a fault code check, and it has come up with a clashing check light and O/D light.

if they are both on then you most likley have a fualt with the engine and the trans...in this case could be the TPS since both the engine and the trans use it.

Is the speedo still working?

Speedo is still working, the fault code flashing was between engine check and O/D Light, one goes on the other goes off, very fast (0.25 seconds)

Where do you live Harvey? I'm in Taupo with a Techstream to pull and clear all those codes and have a look at the sensor values real time.

Do a google search and you'll find out how to read your engine codes by joining up the diagnostic connectors in your engine bay.
