Ever since i had my turbos rebuild, I've been getting the p2263. Turbos spool fine, backpressure reads fine. Should i try replacing sensor even though it's reading? Also started getting p0472 and p040d, could this codes be related to the egt sensor? Being that i did notice egts dropping down to 200, then go up to 500 when at a stop light.
P0472 - Exhaust Pressure Sensor A Circuit Low
Description The DTC indicates the sensor signal is less than the self-test minimum.
Possible Causes:
EP sensor
Incorrect harness connection
VREF circuit open or shorted
P040D - Exhaust Gas Recirculation Temperature (EGRT) Sensor A Circuit High
Description: When the EGRT sensor signal is higher than the specified value, an increment counter advances until the DTC is set.
Possible Causes:
EGCIT circuit short to voltage
EGCIT circuit open
EGRT sensor
P2263 - Turbo/Super Charger Boost System Performance
Description: Indicates that boost pressure is not achieving the calibrated goal by more than a calibrated threshold.
Possible Causes:
CAC system leaks
Exhaust or intake air system leaks
EP sensor biased
Restriction in the EP sensor or tube
Turbocharger vanes sticking
