SOURCE: Ideals rough but drives great where is the map

The map sensor is located just below the alternator on top of the motor. It's easily removed. I just changed one on my intrigue. Their are no screws to remove, it just clips on. It is square in shape and the size of approx., a nickle.

2006 HHR with check engine light flashing. Codes


code 300 means multiple misfire due to plugs, wires, fuel problem including injectors.. 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)
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.

1999 chevy lumina rough idea after warm up


It could be several different things causing this, my first guess would be to look at the EGR port going into the intake. Most times it will clog up and can cause rough idling. You must know how to clean it properly, the EGR valve will have to be pulled as well as the throttle body in order to clean it properly. Also, check for vacuum leaks. It could be other things as well but this is where I would start. Hope this helps. Thanks, Allen with Morgan's Auto Repair 912-282-1602 Waycross, Ga.

91 Oldsmobile 3.1 runs very rough, sets codes 33 and 34


This is a long shot, but it happened to my 3.1 corsica. After all the friggin around and testing everything I discovered it was a loose wire on the back of the computer. It was a wire that went into the plug itself. I wiggled the wires and all of a sudden it kicked in good. I moved my hand away, and there it was again. . The computer is probably located under the dash on the passengers side. Easy to get at. It's worth a try. If not that, you may have a bad computer, but check loose wires first. Let me know how you make out please. If that isn't the problem I'll be glad to walk you through some more tests

Component locator - cannot find the MAP sensor


TESTING-MAP- A vacuum line runs from the sensor mounted high to the intake manifold so it can measure the vacuum in the intake manifold. NOTE: Unusually high or low barometric pressures can generate a false DTC for the MAP sensor. If no driveability symptoms accompany the MAP code, do not replace it.
  1. Connect a MAP/BARO tester to the sensor connector and sensor harness connector. With ignition ON and engine OFF, use DVOM to measure voltage across tester terminals. If the tester's 4-6V indicator is ON, the reference voltage input to the sensor is okay. NOTE: The green light on the tester indicates that the VREF circuit is okay, 4-6 volts. A red light or no light indicates the VREF is either too low or too high.
  2. Measure the reference signal of the MAP sensor. If the DVOM voltage reading is as indicated in the table, the sensor is okay.
    1. Turn the ignition OFF.
    2. Disconnect the vacuum hose from the MAP sensor and connect a vacuum pump in its place.
    3. Apply 18 in. Hg of vacuum to the MAP sensor.
    4. If the MAP sensor holds vacuum, it is okay. If the MAP sensor does not hold vacuum, it must be replaced. Fig. 1: Manifold Absolute Pressure Sensor 84174020.gif

My car idles rough and a machine said the map sensor is running a little high.


If the map sensor is running high, manifold absolute pressure, then I would try checking for a vacuum leak somewhere, or, change the map sensor and see what happens.

Also, check plugs and wires for age.

I'm getting check engine light on my dash, and it tells me that its code P0106. how do i fix this and what is it?


This info coutesy of OBD-II codes.com

Potential Symptoms The following could be symptomatic of a P0106:
  • Engine runs rough
  • Black smoke at tailpipe
  • Engine will not idle
  • Poor fuel economy
  • Engine misses at speed
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
  • Bad PCM (do not assume the PCM is bad until you've exhausted all other possibilities).

2002 chrysler 300 M 3.5 liter immediatly quits after starting.


The ECM is most likey the culprit but I would check ground wires and wiring harness to be sure they aren't faulty. With you telling me the voltage is too high, it pretty much points to wiring but the ECM may have gone bad and its just sending blind signals hence the high voltage. The engine light isn't coming maybe because of the ECM isn't working. Pray it isnt the ECM, its costly but exhaust your options by checking wiring and ground beforing fingering the ECM
