P0113 IAT temp low, current high (18°C, 3.18V) with ambient temp 9°C. My OBD scanner says optimal range is 25-90°C and 1.7-2.8V.
I just completed an oil change and transmission fluid change. I’ve had the car idling on and off the past couple hours while getting it up to temp when doing the trans fluid. The only thing I touched related to the intake is removing the air box to get access to the trans filler plug.
I unplug the MAF and move the wire out of the way, remove the air filter element, tie back the intake tube w/ top of air box, then removed the air box.
When I need to get the fluids back up to temp before the final trans fluid fill, I assemble the air box assembly with filter in it and set it in place, plug in the MAF, and idle the car until it’s up to temp. I made sure everything was assembled and plugged in before starting the car.
I had no error codes throughout all this work. After I buttoned everything up and let the car sit for about 30 minutes, I turned on the car to head out to the gas station and I got 4 DTCs: emissions system (IAT high input), VSA (system error), EPS (system error), and PGM (generic “fault”).
Is there anything that could cause the IAT reading to be low temp (high input)?
I drove around for about 20 minutes and nothing cleared on it’s own. I’ve cleared all the codes and will look at it further in the morning. I have a 1000 mile trip on Sunday so I’m trying to get this resolved tomorrow (Saturday). I appreciate any insight I can get.
