-Turn the main switch to "OFF" and set the engine kill switch to "ON".
-Simultaneously press and hold the "SELECT" and "RESET" buttons for 8 sec.
-After selecting "dl", Simultaneously press and hold "SELECT and "RESET" for 2 or more seconds.

For your error code 20, you want to check both Diagnostics codes 02 and 03.
( 02=ATMOSPHERIC Pressure sensor, 03= INTAKE pressure sensor )

You use the "SELECT" and "RESET" buttons to advance or go back through the code number. They are 01 through 70.

Turn the main switch to "OFF" to cancel this and put the gauge back to normal operation.

I'll have to look up the values in my "Big Book". Do that and let me know the values that are shown for both 02 and 03.

To check the sensor output voltage for intake sensor:

-Turn the key to "ON"
-With a pocket tester, the Positive goes to the Pink/White wire and the negative goes to the Black/blue wire. The voltage should be 4.75-5.25V

For Atmosperic pressure sensor:

-Tester Positive to the Pink wire, and the negative to the Black/Blue wire.
Voltage should be the same as above. ( 4.75-5.25 )

So ther are 2 different sensors?

I have a CPR turbo and the sensor that is on the factory airbox is now on the intercooler, which sensor is this?

I am getting code 20 and went into these diags and D:02=97. D:03=10, What does this mean?.

Can you limp home with code 20 without doing any damage to anything?
