Default error codes turbo

My turbo went out on my 2005 pt cruiser convetible with standard turbo.

I had my turbo replaced and also my oil pump as it went out as a result of turbo blowing.

car runs good now

however, i get an intermittent check engine light with codes 1188 and 234.

After I reset light, it goes away for 3-5 miles then comes back on.

Any advice?????

found this on a porsche page..
02 Turbo... Identified a "0234" fault code today = "Turbo - Super Charger Overboost condition".

The car runs good without hesitation upon acceleration and no odd behaviour.

I did have a CEL diagnosed by the dealer as 0491 and 0492 relating to SAI system but I'm not sure if the two are related, any ideas what I might be up against?

Online search reveals the following...

OBD Code P0234refers to
The PCM disables (bypasses) the supercharger boost and sets a diagnostic trouble code (DTC) to keep from damaging the powertrain (engine or transmission) during potential harmful operating conditions.

Possible sumptoms of OBD code P0234
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes of OBD code P0234
- Brake torque (brake on and throttle at wide open). - Transmission oil temperature (TOT) exceeds calibrated threshold. - Engine over temperature. - Ignition misfire exceeds the calibrated threshold. - Knock sensor (KS) failure

Possible Solutions
Check for other diagnostic trouble codes accompanying P0234, or check appropriate and available PIDs related to the above possible causes.
