[Syty] Overboost

[Marion Cole]

The most usual suspect is the overboost controller and more
specifically, the plastic tube that runs from the turbo body to the
controller relay mounted on the toop of the turbo. It is broken fairly
easily. Can be replaced with a reinforced rubber hose (such as fuel line
hose) but be sure to run a wide circle radius so it does not kink. They
probably broke the plastic tube while doing their work (I speak from my
own experience :-) ).

Did a tune up, including replacing the 02 sensor, and replaced the
exhaust on the 93 Ty we just bought. Runs great except that at WOT it
starts to run strong and then shuts down. It is showing a code 31
Overboost.

 

When the shop replaced the exhaust they eliminated the CAT. Is this
causing the overboost? 

 

If so, what is the best solution? Reinstall a CAT?
