hey... i have about 1500 miles on my metro since buying it. it has gotten a consisten 40mpg so far, and runs pretty good-- it had a new exhaust valve put in, and a recent head rework...not by me but the guy before me. anyways i finally got around to geting the engine code ran-- it comes up as 'P0113 - IAT Circuit Voltage High' from the pinned thread. my question is what is this doing to the car? i should say that i have about 3 or maybe 4 different plugs that are loose, it SUCKS getting a car the someone else unhooked! i think the iat sensor is in the air cleaner-- thats one that is not plugged into. my guess right now is if it is running good, not to worry about it, and work on more important issues with the car. advice?? |

Plug in the IAT (air filter housing) and the code will go away after several drive cycles. |

well, i would but the plug wont fit! i am guessing the breather is off a different model? can you tell me what the effect of no plug is? what sort of drivabilty problems will a high voltage iat code cause?? (gee, he doesnt ask for much, huh??!!!) i am going to meet one of the local guys with a metro--and try to figure out whats missing from thr car. i count 4 plugs loose, and only see 2 places to plug them in, and none of them match up. |

bad bent, THANKS! i bought this one in a state of dissassembly...it looks like the 'canister' is whats missing. thats a charcoal fuel thing, right? the hanger that it goes on is there, with a steel line just naked as all, and the two plug ins are pulled to it and zip stripped up. the iat plug in, and one on the passenger side a bit lower than the throttle body are the two empty plugs... there is a plug in that looks like to should go to the tb, but it is grooved different and wont plug in. none of the three fit either of the two... the last plug in is i think for a/c up front. thanks for the pic, it definitely helped. |

Very glad that that helped. Do you have Air Conditioning? When I put my two engines in I kept the wiring harness taped to the firewall and after the engine was mounted I laid the harness in it's place. I then started hooking stuff up. Nice that the connectors are individual. So, it will take some time but trace the wire harness and you should find the IAT plug somewhere on the harness. It is the next best thing to a MAF sensor I guess. Anyway, it may be hanging off the harness around the alternator, or starter, still stuck to the fire wall, or as far over as the timing belt cover or as low as the #2 O2 sensor, cut off and just wires stuck in the harness But you have the brass thingy sensor in the air cleaner, right? There are two probables as to why you need it connected. If the ECM senses no current then it may think the engine air is cold and compensate by running rich - same principle as the Coolant Temp Sensor. Or it normally is charged and as temp. rises current decreases, which doesn't happen and it thinks it is hot. Which would be OK for FE by faking WAI. I go with probable #1. On the Canister is the charcoal thingy, correct. I double checked and this pic shows where you will connect the EVAP canister. ![]() You should have a vacuum/hose diagram on your hood. Vacuum leaks = high rpm. This is our '96s:
