Default I got some work done today

Today I solved codes 21 and 24. I redid the ground wires by sanding and putting the connector straight to metal. I put dielectric grease on most of the connections. The codes went away.

The only code I have left is 22 MAP/BP out of range.

-I am going to do a Key off, disconnect MAP/BR connector
-Measure Voltage between VREF and SIG RTN at vehicle harness connector
-KOEO
I am suppose to get 4 to 6 volts dc (VREF)

My MAP sensor is brand new so I am going to look more at the wiring side for problem solving.

I think I am also going to reground the wires coming from the O2 sensor.
