How to replace map light when the old light has gone into the above cavity and needs fishing out?

code p 0106 refers to manifold absolute pressure (MAP) sensor / Barometric pressure (BARO)sensor---range performance problem====causes --intake / exhaust leak--wiring---MAP sensor ---BARO sensor code p 0108 refers to same sensors--high input===causes ---wiring short to positive---MAP---BARO sensors --ECM
removing and replacing the battery can corrupt the ECM so use a scan tool to reset it

You'll need to find a wiring diagram an component location chart to check this out . Here is a diagnostic flow chart for trouble shooting this problem ! Do you know how to use a voltmeter ?
DEFINITION: This table diagnoses inoperative turn signals on one side. It assumes that the cornering lamps, hazard lamps, and turn signals on the other side all operate properly.

1

Did you perform the Exterior Lights System Check?
--
Go to Step 2 - yes
Go to Exterior Lights System Check - no

2

1. Disconnect the turn signal flasher connector.
2. Turn the ignition switch to the RUN position.
3. Place the turn signal switch in the appropriate position.
4. Connect a DMM from the appropriate turn signal flasher connector cavity to ground:

?€¢
LH: cavity C (ORN)

?€¢
RH: cavity B (BLK)

Is the voltage within the specified range?
10-15 V
Go to Step 3 yes
Go to Step 5 no

3

Connect a fused jumper between the appropriate turn signal flasher connector cavities:
?€¢
LH: cavity C (ORN) to cavity D (YEL)

?€¢
RH: cavity B (BLK) to cavity F (TAN)

Do the appropriate turn lamps light without flashing?
--
Go to Step 4 yes
Go to Step 6 no

4

Replace the turn signal flasher. Refer to Hazard and Turn Signal Flasher Replacement .
Is the repair complete?

5

Repair the open in the appropriate circuit:
?€¢
LH: CKT 57 (ORN) between S200 and the turn signal flasher

?€¢
RH: CKT 58 (BLK) between S201 and the turn signal flasher

Refer to Wiring Repairs in Wiring Systems.

Repair the open in the appropriate circuit between the turn signal flasher and the IP fuse block:
?€¢
LH: CKT 685 (YEL)

?€¢
RH: CKT 686 (TAN)

MAP stands for Manifold Absolute Pressure. A map sensor is used for measuring vacuum pressure and helps in controlling the air and fuel mixture and well as timing. You have not mentioned which car's Map Sensor you want to replace. However, generally these steps must be followed:Start by Locating the sensor.Disconnect the negative cable for the battery.Unplug wiring harness and the vacuum hose.
- There are two screws that are holding the sensor in place, Unscreq them.Remove the old sensor and Reverse the above procedure to install a new sensor

For the front map lights - gently pry the cover down using a very small screwdriver. The outer-edge (left or right) should be last. the inner portion is where the cover pivots and snaps in.
Once the cover is removed, just unplug the bulb and replace. It is a tube-style bulb...it kind of looks like an old style fuse.

check your coolant temp sensor. possible map sensor.
The MAP sensor is fitted to the front of the throttle body except on 4.7L and 8.0L engines where it is installed on the intake manifold.

1. Remove the air cleaner assembly.
2. On throttle-body mounted MAP sensors, inspect the L-shaped tube from the throttle body to the MAP for cracks, blockage, and damage. Repair as necessary.
3. Unplug the MAP sensor connector.
4. Test the MAP sensor output voltage at the MAP sensor connector between terminals "sensor ground" and "sensor signal". With ignition ON and the engine OFF , the voltage should be between 4-5 volts.
5. Check voltage across the same terminals with the engine running at idle at operating temperature. Voltage should be 1.5-2.1 volts.
6. Test MAP sensor supply voltage at sensor connector between terminals "sensor ground" and "5v supply" with the ignition ON and engine off, voltage should be 4.5-5.0 volts.
7. Test the MAP sensor ground circuit at the "sensor ground" of the MAP connector, voltage should be less than 0.2 volts. If not inspect for open harness from pin 4 of PCM harness and terminal A . If no voltage is present, proceed to the next step.
8. Turn the ignition OFF .
9. Disconnect the PCM harness from the PCM.

WARNING Testing the wiring harness with the PCM still connected can cause serious damage to the processor. ALWAYS disconnect the PCM before testing the wiring harness, unless instructed otherwise.

1. Test the MAP sensor output voltage at the PCM connector. At the PCM cavity A-27 , the voltage should be about 5.0 volts.
2. Check the voltage at PCM cavity A-17 . It should be 5.0 volts.
3. If all of the above tests pass, plug in PCM wiring harness and MAP sensor connector.
4. With the ignition in the ON position, and the engine OFF , remove the tube from the throttle body to the MAP sensor.
5. Connect a vacuum pump to the nipple on the MAP sensor, and pump the sensor to 20-27 in. Hg. Check the sensor output voltage, it should be below 1.8 volts. If not, replace the MAP sensor. If the voltage is OK, proceed to next step.
6. Relieve vacuum pressure on the sensor, then check the output voltage. The voltage should be 4-5 volts; if not, replace the MAP sensor.
7. Install the air cleaner assembly.

2004 jeep grand cherokee, brake lights do not work, no power at fuse cavity 23 and the fog lights are also out but the dash indicator is working.

Water in spark plug holes in heads!!!!! Spark is jumping through coil plug boots. Remove coil pak and dry boots, blow compressed air to dry out spark plug holes. they go straight down from fue rail. Good luck with the passenger side by fire wall. its a tuffy

i didnt think they used that engine in that car unless it is out side the U.S. well anyway on the side of the dome shape intake manifold(shoul be side closest to belts) there is either a sensor with a 3 wire plug going to it(map sensor) or just a vacuum hose whichever one it is--remove it and youl see a round removable lid of sorts. take the lid off and the pcv valve is down inside that cavity.

Grab the FRONT of the entire light housing and pull. The entire unit pops right off,
