2007 softail deluxe wiring diagram for map sensor

I'm assuming your referring to a P0107 code as there is normally four numbers in a DTC code. Were there any other DTC codes? Sometimes another issue can cause other codes to appear.
Get the actual wiring checked to the MAP sensor. There might be a short or a broken wire causing an issue with the sensor.

code p 107 refers to manifold absolute pressure (MAP) sensor / barometric pressure(BARO) sensor --low input===causes ---wiring short to ground---MAP sensor---BARO sensor ---ECM

DTC P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)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. Experience indicates that the most likely solution is to replace the thermostat.
DTC P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low InputThe Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum).
This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low. Confirm this measures conditions.

Keep in mind that will need using a scan tool with the Key on and engine running, monitor the MAP sensor voltage. If it is reading less than .5 volts, turn engine off, unplug the MAP sensor and, using a DVOM (Digital Volt/Ohm Meter) check for 5Volts on the 5 Volt reference circuit.


DTC P0401 - Insufficient EGR Flow
This fault code most likely means one or more of the following has happened:

• The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
• There is a blockage in the EGR (tube), most likely carbon buildup
• The EGR valve is faulty
• The EGR valve may not be opening due to a lack of vaccuum

Now, about the possible solutions in fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.

• Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
• Clean out the EGR valve and/or tubing to remove deposits
• Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
• Replace the DPFE sensor (with a good quality / OEM one)
• Replace the EGR valve

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.



Thank you for using FixYa, have a nice day.

What does that mean?

The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum).

Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:

• Hard to start
• Long cranking times
• Sputtering/missing
• Blowing black smoke
• Poor fuel economy
• Dies intermittently
• MIL(Malfunction Indicator Lamp) illumination

Causes

The causes of a low MAP sensor signal circuit (P0107) could be any of the following:

• Bad MAP sensor
• Open or short in the signal circuit
• Open or short in the 5 Volt reference circuit
• Ground circuit open or shorted
• Bad PCM

P0107 -- CONTINUOUS
Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.

Possible cause - faulty internal BARO sensor (PCM)

Perform KOEO On-Demand Self Test. Is P0107 present?
Yes, REPLACE PCM. CLEAR DTC and RETEST.
No, P0107 is intermittent fault. CLEAR DTC. If DTC reappears, REPLACE PCM.

If you keep getting it, a new PCM is the only fix.

Hi, check the connector and wiring on your MAP sensor. If that looks good, back-probe the sensor connector with the engine running, using a voltmeter. First verify there is approximately 5 volts DC between the gray and orange wires. If not, remove the connector and probe the connector terminals. If there is still less than 4.8 volts at the connector, suspect the wiring from the PCM is bad. If the voltage is good off the sensor but not on the sensor, the sensor is bad.
If the voltage is good, next check the function of the sensor. Measure the voltage between the orange and green wires. Open and colse the throttle to see if the voltage changes with throttle opening. If it does, the sensor is probably fine. Please let me know if you have questions, and thanks for using FixYa.

MAP sensor is #1 in the diagram below.

p0107 may be a leaking intake or somebody changed the pcv valve and left the o-ring off of it.

P0107 - Manifold Absolute Pressure/Barometric Pressure Circuit Low Input

The Manifold Absolute Pressure (MAP) sensor responds to changes in the intake manifold pressure (vacuum). 5 Volts is supplied to the sensor from the PCM (powertrain control module). Inside the MAP sensor is a resistor that moves in relation to manifold pressure. The resistor varies the voltage between about 1 volt to 4.5 volts (depending on engine load) and that voltage signal is returned to the PCM to indicate manifold pressure (vacuum). This signal is essential for the PCM to determine fuel delivery. A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low.

Potential Symptoms: Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include:
* Hard to start
* Long cranking times
* Sputtering/missing
* Blowing black smoke
* Poor fuel economy
* Dies intermittently
* MIL(Malfunction Indicator Lamp) illumination

Causes: The causes of a low MAP sensor signal circuit (P0107) could be any of the following:
* Bad MAP sensor
* Open or short in the signal circuit
* Open or short in the 5 Volt reference circuit
* Ground circuit open or shorted
* Bad PCM

Possible Solutions: First, using a scan tool with the Key on and engine running, monitor the MAP sensor voltage. If it is reading less than .5 volts, turn engine off, unplug the MAP sensor and, using a DVOM (Digital Volt/Ohm Meter) check for 5Volts on the 5 Volt reference circuit.

1. If there is not 5 Volts on the reference circuit, then check for the reference voltage at the PCM connector. If it is present at the PCM connector but not the MAP connector, repair the open in the reference circuit between the PCM and MAP harness connector. If 5 Volt reference is NOT present at the PCM connector, check powers and grounds of PCM and repair/replace as needed. (NOTE: On Chrysler products, a shorted Crank sensor, Vehicle speed sensor or any other sensor that utilizes the 5 Volt reference from the PCM can short out the 5 Volt reference. To fix simply unplug each sensor one at a time until the 5 Volt reference reappears. The last sensor unplugged is the shorted sensor.)

2. If you have a 5 Volt reference at the MAP connector, jumper the 5 volt reference circuit to the signal circuit. Now check the MAP voltage on the scan tool. It should be 4.5 to 5 Volts. If it is, replace MAP sensor. If not, repair open/short in the signal circuit wiring and re-check.

3. If all appears okay, perform a wiggle test. Start engine and manipulate the harness, connector and tap on the MAP sensor. Note any changes in voltage or engine speed. Repair connector, harness, or sensor as needed.

4. If the wiggle test checks out, use a vacuum pump (or just use your lungs) to draw a vacuum on the MAP sensor vacuum port. As you add vacuum the voltage should decrease. With no vacuum, the MAP sensor should read approximately 4.5 volts. If there is no change in MAP sensor reading on the scan tool, replace MAP sensor.

MAP Sensor DTC's: P0105, P0106, P0107, P0108 and P0109.

Hope helps (remember rated and comment this).
