SOURCE: cant find the iat sensor on 91 s10

The IAT or MAT sensor (as equipped), is a thermistor (resistor which changes value based on temperature) mounted either in the air intake snorkel or the manifold (depending on the application).

SOURCE: need location of the erg sensor 2000 ford ranger

The egr valve has two sensors. One is an EGR position sensor which is physically attached to the EGR valve. The other sensor is the DPFE (Delta Pressure Feedback EGR) sensor, commonly called the EGR pressure sensor. It's location varies depending on the engine you have. You can fine this sensor by following the vacuum hose on the EGR valve. It will be with in inches of the EGR valve. The sensor will be black (plastic) or silver (metal), have two or three vacuum ports and an electrical connection on it.

The vacuum pressure sensor is a high failure item on fords. Any Ford parts department will have one in stock, as well as some aftermarket parts stores.

The new sensor may not look exactly the same as the old part, but will have all the hook ups as the old one. You may also need to replace the vacuum hose to the sensor as well

SOURCE: locating the iat sensor on a chevy tahoe 2008

Yes. That is exactly it. The Air Intake Temp Sensor is built into the Mass Air Flow Sensor on the Air Filter Box. Below is a picture...

I personally have not connected one of these Chips to a Tahoe...What I can provide you with, is the Connector Diagram so you know exactly what Wires you need to Splice in to. See below...

SOURCE: installing chip and want to double check wiring. Need to find IAT/MAF sensor diagram for 2003 Ford Ranger

Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

4x4 4.0l V6. What are the probable causes of DTCs P0112, P0117, P0122, P0513, P0556, and P0565?


code p 0112 refers to intake air temp (IAT) sensor --circuit malfunction===cause --wiring short to graound--wiring short to positive --IAT sensor ---ECM
code p 0117 refers to engine coolant temp (ECT) sensor--circuit malfunction=== causes --coolant thermostat---wiring short to ground--wiring short to positive ---ECT sensor
code p 0122 refers to throttle position (TP) sensor A/ accelerator pedal position (APP) sensor A low input === causes wiring short to ground--TP/APP sensor --ECM
There are 3 responses to p 0122 and all refer to TP switch /sensor plus wiring open /short to ground/ short to positive
code p 0513 refers to incorrect immobilizer key=== causes immobilizer system
code p 0556 refers to brake booster pressure sensor---circuit range / performance=== causes --wiring---poor connection---brake booster pressure sensor---ECM
code p 0565 refers to cruise control master switch. off signal --malfunction === causes wiring---cruise control master switch--ECM
by reading all the codes you will see that common causes are wiring problems and ECM so may be a quick check would be to replace the ECM with a known working unit first and work back from there

I'm trying t locate my IAT sensor on my ford escort 1994 and i cant find it


it is located on the inlet for the throttlebody on a section between the throttlebody and the air intake tube from the airbox. Do you have a North American model or a European model? The European model didn't require an IAT sensor. Just the North American model to meet EPA requirements. If it's a North Americal model, the sensor should be located in the air cleaner and have 2 small hoses attatched to it. have a good day !!

2002 Ford Ranger surges when air temperature is cold


It could be the air-fuel ratio is too lean and isn't correcting for a low air temperature. I have noticed a couple of Fords doing the same thing, but only at light throttle and the problem disappears as soon as the engine is put under load.

The Ford technical hotline might be able to provide an answer if you can find a mechanic willing to call them on your behalf - they won't talk to unregistered users.
