I got a 99, 5 speed accord. i changed the head gasket on it and now i got a P0112 code on my ecu. That's calling for the Intake air temperture sensor low input, i changed the intake air temperture (IAT), changed the Engine coolant temperture (ECT), and the Radiator fan switch. and the ECU is still giving me the same code. any one out there know what else to check.. oh and my engine wont rave up to more than 4,000 RPM.

start looking at your wiring, might just be a bad connection somewhere

 

do you mean looking at other parts that the wire runs from and to??? or look at other parts that might have not been plug up.. oh and is there a way to check and see if i got power coming to it from the ecu???

 

yea, check the harness from the sensor back to the ecu, make sure all the clips at the junctions are tight and secure....

if you got a low voltage code for that sensor, you know you have power, if there was no power i think it will give you a p0111

 

well before i took the head out and change the head gasket my fan didn't work until the motor gets hot, but now my fan works all the time, even before i turn on the engine. is there a reason why , and do you have pictures of sensor and their plug ups in color.

 

no, i dont have pics....

but if your fan is on all the time, then take a look at the engine coolant temp sensor... when some of them short internally, it turns the fans on

 

i have a 00 accord f23a1 vtec i wrecked the car and had it fixed but but key was lost during towing process and a lotta bs went down with the tow truck driver due to..
engine still wont start new key programmed and went back to collumn ignition (had push button start but was just using the key for the immobilizer sensor), but if i swap the 96 accord ecu with a push button start with this by pass the immobilzer system,cause 95 accord was OBD1 and the ecu plug dnt match and 96 was crossover so will the 96 ecu work plz help this is killin me this car is my daily driver/project but now its in my garage and wont start

 

wow, way to hijack this thread... id say tow it to a dealership, and have them reprogram everything.
