Click--> Chandler MotorsportsThe PartRecent Feedback ReceivedAbout the partNewRevised designOEM FitTop Shelf BrandLIFETIME WARRANTY0Z3FRUF591S9Typical driveability symptoms that may be MAP related include:Surging.Rough idle.A rich fuel condition, which may cause spark plug fouling.Detonation due to too much spark advance and a lean fuel ratio.Loss of power and/or fuel economy due to retarded timing and an excessively rich fuel ratio.A vacuum leak will reduce intake vacuum and cause the MAP sensor to indicate a higher than normal load on the engine. The computer will try to compensate by richening the fuel mixture and retarding timing -- which hurts fuel economy, performance and emissions.MAP SENSOR CHECKSFirst, make sure engine manifold vacuum is within specifications at idle. If vacuum is unusually low, there may be a vacuum leak (leaky hose connection, intake manifold or throttle body gasket, power brake booster, etc.), an exhaust restriction (clogged converter), or an EGR leak (EGR valve not closing at idle).A low intake vacuum reading or excessive backpressure in the exhaust system can trick the MAP sensor into indicating there's a load on the engine. This may result in a rich fuel condition.A restriction in the air intake (such as a plugged air filter), on the other hand, may produce higher than normal vacuum readings. This would result in a load low indication from the MAP sensor and possibly a lean fuel condition.Next, check the sensor's vacuum hose for kinks or leaks. Then use a hand-held vacuum pump to check the sensor itself for leaks. The sensor should hold vacuum. Any leakage calls for replacement.An outright failure of the MAP sensor, loss of the sensor signal due to a wiring problem, or a sensor signal that is outside the normal voltage or frequency range will usually set a diagnostic trouble code (DTC) and turn on the Check Engine light. use a scan tool to check MAP sensor input and fault codesMAP SENSOR SCAN TOOL CHECKSOn 1995 and newer vehicles with OBD II self-diagnostics, a DTC code P0105 to P0109 would indicate a fault in the MAP sensor circuit.On older pre-OBD II vehicles, the MAP codes are:General Motors: Codes 34, 33, 31Ford: Codes 22, 72Chrysler: Codes 13, 14On vehicles that provide data stream through a diagnostic connector and allow a scan tool to display sensor values, the MAP sensor's output voltage can be read and compared to specifications. Basically, you want to see a quick and dramatic change in the MAP sensor signal when the throttle on an idling engine is snapped open and shut. No change would indicate a sensor or wiring fault.If the sensor is reading low or there is no reading at all, check for proper reference voltage to the sensor. It should be very close to 5 volts. Also check the ground connection. If the reference voltage is low, check the wiring harness and connector for looseness, damage or corrosion.Scan tools that display OBD II data will also display a "calculated load value" that can be used to determine if the MAP sensor is working or not. The load value is computed using inputs from the MAP sensor, TPS sensor, airflow sensor and engine speed. The value should be low at idle, and high when the engine is under load. No change in the value, or a higher than normal reading at idle might indicate a problem with the MAP sensor, TPS sensor or airflow sensor. MAP sensor waveformMAP SENSOR TESTSA MAP sensor can also be bench tested by applying vacuum to the vacuum port with a hand vacuum pump. With 5 volts to the reference wire, the output voltage of an analog MAP sensor should drop, and on a Ford digital MAP sensor the frequency should increase.An analog MAP sensor's voltage can also be read directly using a voltmeter or oscilloscope. A digital MAP sensor's frequency signal can be read with a DVOM if it has a frequency function, or an oscilloscope. The leads would be connected to the signal wire and ground.Warning: Do NOT use an ordinary voltmeter to check a Ford BP/MAP sensor because doing so can damage the electronics inside the sensor. This type of sensor can only be diagnosed with a DVOM that displays frequency, or a scope or scan tool.Another way to check out a Ford digital MAP sensor circuit is to input a "simulated" MAP sensor signal with a tester that can generate an adjustable frequency signal. Changing the frequency of the simulated signal should trick the computer into changing the fuel mixture (look for a change in the injector pulse width signal).No change would indicate a possible computer problem.MAP SENSOR REPLACEMENTIf a MAP sensor needs to be replaced, make sure the replacement is the correct one for the application. Differences in calibration between model years and engines will affect the operation of the engine management system.ManufacturerPart NumberGMOEM16212460AC Delco213-331Standard Motor Parts SMP, KEM Parts,AS60Airtex5s2398BWDEC1686DelphiPS10002-11B1WellsSU1176Recent Feedback We've Received!Frequently Asked QuestionsShipping Discounts - Most of our listings provide free shipping, so understandably we can't discount lower than free.

Cancer, Alzheimer's, Cystric Fibrosis, BSE and Emphysema ResearchDiseases such as Alzheimer's disease, cystic fibrosis, BSE (Mad Cow disease), an inherited form of emphysema, and even many cancers are believed to result from protein misfolding. When proteins misfold, they can clump together ("aggregate"). These clumps can often gather in the brain, where they are believed to cause the symptoms of Mad Cow or Alzheimer's disease. Stanford University has taken up a project to use Distributed Computing to attempt to understand and hopefully one day solve the problem of misfolds called Folding at Home. We take part in the project and you can too, very simply. All it requires is for you to install the program on your computer, it runs on your idle CPU time. The overall performance cost to run the program is under 1% at full usage. We run it on all computers in the warehouse and I run it on my personal computer.http://folding.stanford.edu/English/DownloadWhere you can download the installer.http://en.wikipedia.org/wiki/Distributed_computingThe technique used to process the calculationshttp://folding.stanford.edu/English/ScienceLink to understand what Protien Folding is.We pack in with every order instructions of how to install and use the program along with its purpose. We also include information of how to join our TEAM! We operate a philanthropist arm of our company FoldingAtWork.ORG (not associated with Folding at Home). The goal is to recruite as many users, universities, customers, clients, friends, business partners and whoever else we can to take part in the project. Another way we contribute to research is by offering space in our warehouse for folding computing. If you would like to donate to us, we offer donation packages which we use to buy GPU farms, computers and other equipment used. You name the computer, get a picture of its home in the warehouse and are provided with a link to track the calculations processed thanks to your help.Contacting UsThe absolute best way to contact us is through the eCRATER messaging system. Questions sent through email, or directed through the phone are generally the slowest to be replied to. So if you have a question or concern, its always best to message on the bay! The exception to that rule is for wholesale orders, which we like to have documented through email. It's easiest for us to send a catalog or a price quote through email in that case! We reply to our messages on average once per day Monday through Friday excluding holidays, so take that in mind when
