Error code P0475
I have read a lot of the post in this forum about the same issue but I can't figure out how to fix mine. I went and got my truck smog and it failed because of this code. I then changed the sensor cleaned out the tube and I still can't figure out how to get rid of the error code? any advice

P0475: Exhaust pressure control valve malfunction / Open/grounded ckt., solenoid /open/shorted, failed PCM.
DIAGNOSTICS
1. possible causes:
a. shorted to power
b. open/grounded circuit
c. damaged solenoid
d. damaged PCM
e. Disconnect EPR harness connector.
f. Measure resistance between Pin A and ground.
g. Deleted EBPV
2. Do you have Power to the GY/R wire/pin?
3. Measure resistance across EPR coil contacts A and B. Spec: 2.5 - 12 ohms? If not, replace regulator.

Attached is a link to a post about adding a resistor in-line in the plug if it is unplugged intentionally or if it has been deleted. You will be fooling the PCM.
