2000 ford explorer P0113 code, replaced the MAF, cracked vacuum

2000 ford explorer P0113 code, replaced the MAF, and cracked vacuum hoses. Reset the code with both the code reader and disconnecting the negative terminal. Light stays off for about an hour then comes back on. Can it be the egr vacuum solenoid?


Here's what it is doing. During the summer time when the vehicle is warmed up and it is hot outside the vehicle dies. Have to let it sit for about 20 minutes, like it is cooling down, then it will run for about 5 minutes before doing it again. any help would be much appreciated. Thanks for looking.

    Not to familiar with these. I have had my upper and lower intake gaskets replaced recently, so i am hoping that wasn't $800 down the drain. When you say key on engine running trouble code test, do you mean a OBDII scanner connected while it is running? I am trying to fix this problem now as i just spent over 1k last week at the mechanic to find out he fixed nothing.

  • exploder07 May 18, 2009

    the mechanic i took it to did hook it up and was watching it on the OBDII scanners, showing different graphs and things i wasn't to familiar with. But he was sure it was the upper intake gaskets, which were replaced about a week before him, then about three days ago by him, with no success.

    Nice try fuzzsocks...However, On my explorer the IAT sensor and the MAF are wo in one. It has both sensors together instead of having the IAT on the Air hose itself. Two mechanics were baffeled for a while until they finally figured it out. Thanks for the attemp though

    The vehicle has no issues starting, only staying running. Even when the vehicle stalls after being warmed up it will run as long as you hold down the accelerator.

    yes it is the active test that we run with the Ford scanner called an NGS.

P0113 code indicates that the intake air temp sensor has Hi voltage. This sensor is located in the air intake near or in the air cleaner. It is a 2 wire sensor that looks like it does nothing. It measures air temp coming into engine and then the computer knows what kind of fuel mixture it should be delivering. This may be something to look at. The reason the check engine light comes on later is that the computer only self checks at certain times. Rate me if this helps

    When this problem occurs, is it a fuel problem or spark problem.? If you lose spark at this time you might want to see if the voltage at the coil is above 9.5 volts. I have had a problem with the connector that feeds the ignition system. It is deep inside the harness that feeds many other circuts. This is only a suggestion. You must know which system has failed to get a "no start" condition.

    Is the complaint that it won't idle when warm? If so , perhaps the idle air control is not responding to computer demands.

  • Moe May 18, 2009

    Another problem just occurred to me. If your engine has a minimum idle spec. that requires the dissconnetion of the IAC and set the throttle plate to a specified RPM.. If this is required as an adjustment for "tune-up" , then there is a possibility that the air intake has a build-up of carbon between the throttle plate and throttle bore. This spec is called "Minimum air rate" Does this help?

  • Moe May 21, 2009

    ALERT Check for EGR operation. If the egr were to leak at idle then your problem is occurring. To check the egr valve operation, remove the vac hose to the valve and see if there is any change to the idle. If not then the control to the egr is o/k. Apply vac to the egr and check if engine running changes. If the engine still runs the same then the egr valve is leaking internally. Replace egr.

2005 ford taurus with a p0113 code saying high circuit


p0113 means you are getting a very high voltage reading from the IAT sensor to the ECU. Usually this is because the IAT has become faulty or bad. Replace and clear codes it should go away.

This shows list of codes. You have so many faults hard to know where to start. Was new engine an EXACT match for the old one? If not, did you change ECM? Appears MAF is not connected or bad, and also #1 injector circuit is bad. Others also.

Replaced the MAF. Still have the P0113 code. Car runs fine. Cannot find another intake air temperature sensor anywhere on the vehicle! Where is it?


code p0113 does not refer to a MAF sensor so replacing that was a waste of money=== It refers to intake air temperature (IAT) sensor---circuit malfunction====causes --wiring open circuit/short circuit to positive--wiring short circuit to ground---ground wire defective---IAT sensor---ECM.
Replace the IAT and check the wiring is in good condition and the connectors are clean and tight.

P0113


I show an intake air temp sensor used on all three engines. It uses a gray and gray-red wire. I would expect it to be in the air filter housing or hose. You can check with an auto parts store for a visual.

Ford e150 codes: p0401, p1401 and p0174. read the more details to see what the symptoms are.


Stop, DO NOT replace expensive parts or O2 sensor! Ford Explorer codes p0174 , p0401 , rough idle and check engine light on. First thoroughly check all of the hoses and elbows connected to the intake and EGR (vacuum system) for splits, cracks, holes or tears, this could quickly cause these codes and fixes for less than $10. Check all connectors and the EGR valve sensor it could have a crack as well, inspect thoroughly because a split sensor could appear attached to the vacuum hoses but hoses could just be sitting there not actually attached due to a split or crack. This was my problem replaced the EGR valve sensor and the two little vacuum hoses attached to them for $50-60 with in stock parts at the local parts store. Took less than 10 minutes to replace and is easily accessible, the check engine light turned off immediately without having to reset the codes by disconnecting the battery, idle became normal and fuel efficiency better. If you have THOROUGHLY inspected every hose, connector and elbow and found no issues, clean the MAF with electrical contact cleaner ( let dry) and clean the EGR with carbon cleaner. A dirty MAF or EGR could also cause these codes to pop up. If this still doesn't work, then consider replacing the EGR, if that isn't it then try the O2 sensor. Good luck!

Windstar 2000 3.8. Runs fine. Checked for codes and got p0171 and p0174. Cleaned the MAF sensor. Went to erase codes and found the there is a third one in there now. p0113. What is wrong?


The upper intake manifold gaskets and isolators (the bolts that hold the manifold down) leak and cause the p0171 and p0174. The reason they leak is due to a missing baffle in the front valve cover which allows some oil into the upper intake which swells the gaskets and wears them. The manifold gaskets and valve cover should be replaced. But before having this done check to see if the black plastic hose on the back of the rubber intake hose(between the throttle body and maf) has dislodged. This happens alot when a new air filter is installed and will cause the same codes.

Ford explorer ,4 litre. have code of P0171


You could be right but before going to all that trouble of replacing the intake gasket take a close look at the MAF (Mass Air Flow) sensor. Also look for a vacuum leak downstream of the MAF sensor. The MAF sensor may be dirty especially if you are using an "oiled" air filter and it was over oiled. Remove the MAF sensor and clean it with electronic cleaner. Make sure it is dry before reinstalling. If it is damaged, replace it. Also replace the fuel filter as a partially clogged filter has been know to set this code on some vehicles. Check all vacuum hoses and replace as necessary.

Code #P0171 & code #P0174


The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.
