Trouble code po113
Will cause limphome ,low power, and mpg bad, and CEL glow.
IAT is major sensor on MAP EFI.
the IAT reads too high, id bet it's unplugged.
or was removed and dropped to the pavement and broken inside.
the eCU reports this when the input hits near 5vdc.
this is and open circuit stated.
fell off, wires bad. connector bad. dead open sensor bad.
my fsm has no IAT resistance table. (sad)
my garage is 60f and my sensor reads 16k ohms (16,000)
with hot water (tap at sink) running over it , it might read
3000 ohms, or 3k. it is a NTC sensor, more heat , lower ohms.
the sensor is double locked, so never fall off.
slide red lock up, and mush lever down and pull conn. off sensor.
3 steps.
THE fsm STATES
K21) IAT SIGNAL CIRCUIT SHORTED TO VOLTAGE (12V?)
(K21) IAT SIGNAL CIRCUIT OPEN (FELL OFF?)
(K900) SENSOR GROUND CIRCUIT OPEN (FELL OFF)
IAT SENSOR (BAD)
POWERTRAIN CONTROL MODULE (PCM) nah.
