I have the codes, definitions but still dont understand what defs mean.

Hello,

My 96 Buick Riviera gave me 3 error codes yest which made the SES come on.
WHen in the morning today SES did not go off, I checked them out with Actron super scanner and this is what I got:


1/3
P0102
MAF or VAF A circuit low input

2/3
P0113
IAT Sensor 1 Circuit high input

and

3/3
P0113 pd
IAT Sensor 1 ciruit input

(I have no idea what "little letters "p d" mean next to the error code. THis wasnt in the database.


ANyway Im trying to figure out whats going wrong. Thank you

Update:


I erased the 3 codes posted earlier and drove the car - nothing. However 2nd drive, I was driving move intensely , going almost to 4 k RPM when the 2 IAT Sensor codes appeared again, triggering SES light.

This time, P0113 pd is 1/2, P0113 is 2/2.

thank you.
