SOURCE: 2005 jeep liberty diesel code # p0101 map- sensor out of range what is map

The MAP sensor (MANIFOLD ABSOLUTE PRESSURE) changes voltage or frequency as intake manifold pressure changes (air flow increases or decreases). The engine's computer uses the reading to advance or ****** engine timing. On older, non-fuel injected engines the vacuum advance on the distributor did basically the same thing.
The MAP sensor also works with other sensors on the Jeep engine, specifically the Throttle Position Sensor (on the throttle body) and Crank Position Sensor (on the transmission bell housing) to control other fuel flow and ignition timing functions.
If you're having problems with the MAP sensor, or are getting a Check Engine light and code for the MAP sensor keep in mind that other problems may cause that error code.
Bad vacuum hoses, vacuum leaks, bad EGR valves, intake manifold leaks, clogged air filter can all affect the MAP. sensor. To know for sure all the other sensors should be checked for correct voltage and perimeters
Also, if you have done any mods to the engine, especially intake, exhaust and ignition mods you may get an error code for the MAP or incorrect reading and a resulting loss in power or increased fuel usage.
The map sensor is easy to change with a couple screws off the Throttle body.. The part the air inters (the air breather). Buy one from the auto parts store if your sure that is the problem and just replace it..There is no adjustments to it...

It really sounds to me that you have a small vacuum leak in a line somewhere.You can try spraying the motor vacuum lines with soapy water with the vehicle running to find a leak. Also listen and feel under the dash for leaks and hissing sounds.
Hope this helps.......

SOURCE: how long does it take check engine light to go off

you can take of the ground of the battery of the car for 30 minutes and the computer will reset. if you drive around without reseting the computer might figure it out after 30 miles.

SOURCE: i have a 2004 Isuzu Axiom, my check engine light

You may have actually had a faulty MAP that needed replace. Thing is that any time you get a "check engine", the cruise will be disabled. you must clear the code, by either a trouble code diagnostic tool, or disconnect the battery for about five minutes. Codes will clear, and cruise will start working again.

2004 Isuzu Ascender keeps misfiring,losing acceleration and sputtering when stopped at a red light or stop sign. Changed camshaft position censor.Found oil all over the threads on two plugs


The first thing i would do is replace plugs after checking if wires areok. I thought my fuel pump was going out but all it was, was bad plugs and wires. i replaced them and my gas mileage went up 50%.

P0106 - MAP/Barometric Pressure Circuit Range/Performance ProblemOBD-II Trouble Code Technical Description

Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem

What does that mean? The Powertrain Control Module (PCM) uses the Manifold Absolute Pressure Sensor (MAP) to monitor engine load. (NOTE: Some vehicles have a Barometric Pressure (BARO) sensor that is integral to the Mass Air Flow (MAF) sensor and do not have a MAP sensor. Other vehicles have a MAF/BARO and a redundant MAP sensor where the MAP sensor functions as a backup input in case of MAF failure.) The PCM supplies a 5 Volt reference signal to the MAP sensor. Usually the PCM also supplies a ground circuit to the MAP sensor as well. As the manifold pressure changes with load, the MAP sensor input informs the PCM. At idle the voltage should be 1 to 1.5 Volts and approximately 4.5 Volts at Wide Open Throttle (WOT). The PCM looks for any change in manifold pressure to be preceded by a change in engine load in the form of changes in throttle angle, engine speed, or Exhaust Gas Recirculation (EGR) flow. If the PCM doesn't see any of these factors change while detecting a rapid change in MAP value, it will set a P0106.
Causes A P0106 could be caused by:

  • Bad MAP sensor
  • Water/dirt intrusion affecting MAP sensor connector
  • Intermittent open in the reference, ground, or signal wire for the MAP sensor
  • Intermittent short in the reference, ground, or signal wire for the MAP sensor
  • Ground problem due to corrosion causing intermittent signal problem
  • A break in the flexible air intake duct between the MAF and the intake manifold
  • Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities)
Possible Solutions Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading. They should be roughly equal. The voltage for the MAP sensor should read approx. 4.5 volts. Now start the engine and look for a significant drop in the MAP sensor voltage indicating the MAP sensor is working.
If the MAP reading doesn't change perform the following:
  1. With the Key on, engine off, disconnect the vacuum hose from the MAP sensor. Using a vacuum pump, pull 20 in. of vacuum on the MAP sensor. Does the voltage drop? It should. If it doesn't inspect the MAP sensor vacuum port and vacuum hose to manifold for a restriction of some kind. Repair or replace as necessary.
  2. If there are no restrictions, and the value doesn't change with vacuum, then perform the following: with the Key on and engine off and the MAP sensor unplugged, check for 5 Volts at the reference wire to the MAP sensor connector with a Digital Voltmeter. If there is none, check for reference voltage at the PCM connector. If the reference voltage is present at the PCM connector but not the MAP connector, check for open or short in the reference wire between MAP and PCM and retest.
  3. If reference voltage is present, then check for existing ground at the MAP sensor connector. If it isn't present then repair open/short in the ground circuit.
  4. If ground is present, then replace MAP sensor.
Other MAP sensor trouble codes include P0105, P0107, P0108 and P0109.
P0128 OBD-II Trouble Code Technical Description

Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)
What does that mean? This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. Similar codes: P0125
In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolantmag-glass_10x10.gif temperature (ECT) sensor reading, and the speed of the vehicle.

Causes A code P0128 may mean that one or more of the following has happened:

  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor
Possible Solutions Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat

I have a 2005 Isuzu ascender, the gauge light keeps coming on. The oil gauge drops to zero. I have gotten an oil change and new filter. What can the problem be now?


It could be a bad oil sending sensor, or the oil pump. When it drops, does the gauge stay on zero or fluctuates. The sending sensor isn't to bad to replace or cost wise, but pump is a different story. Have someone check the sending unit or just have it replaced to see if that's the problem.

2004 Dodge Stratus MAP Sensor


Alright I think I might have the same problem. I am trying to add the photos of where the sensor is but I am not sure it is going to work. If the pics do not come through, then just look to the left of the transmission dip stick and I believe it is the on the back side of the engine. It has a red clip that is holding on the wires to the sensor and it is the left one of the two clips back there. Also before replacing the sensor check out the link below. Another person was having the same problem and fixed it without replacing the sensor. The guy helping him said that if you have bad spark plugs or wires it could trip the MAP sensor trouble code. Hope this helps.
