Conditions for Clearing the MIL/DTC

The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

DTC P0106

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Powertrain Control Module (PCM) Connector End Views or Engine Controls Connector End Views
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Inspect for the following conditions: Any disconnected, damaged, or incorrectly routed vacuum hoses Any damage or fractures to the manifold absolute pressure (MAP) sensor housing A missing or damaged MAP sensor seal Restrictions or debris in the MAP sensor vacuum port An Intake manifold vacuum leak Did you find and correct the condition?	-	Go to Step 22	Go to Step 3
3	IMPORTANT: The following sensors share a bused low reference circuit within the powertrain control module (PCM) and a common ground. A high resistance on that shared portion will shift both sensors. Turn ON the ignition, with the engine OFF. Observe the MAP Sensor parameter with a scan tool. Observe the BARO parameter with a scan tool. Compare the values. Is the difference between the MAP Sensor parameter and the BARO parameter more than the specified value?	5 kPa	Go to Step 10	Go to Step 4
4	IMPORTANT: The Altitude vs. Barometric Pressure table indicates a pressure range for a given altitude under normal weather conditions. Weather conditions consisting of very low or very high pressure and/or very low or very high temperature may cause a reading to be slightly out of range. Accurately determine the altitude for your location. Observe the MAP Sensor kPa parameter with a scan tool. The MAP Sensor parameter should be within the specified pressure range for your altitude. Refer to Altitude vs Barometric Pressure . Is the MAP Sensor parameter within the specified range as indicated on the Altitude vs. Barometric Pressure table?	-	Go to Step 5	Go to Step 10
5	Observe the MAP Sensor kPa parameter with a scan tool. Start the engine. Does the MAP Sensor kPa parameter decrease?	-	Go to Step 6	Go to Step 10
6	Turn OFF the ignition. Remove the MAP sensor from the engine intake manifold. Leave the MAP sensor connected to the engine harness. Connect a vacuum pump to the MAP sensor. Turn ON the ignition, with the engine OFF. Observe the MAP Sensor parameter with a scan tool. Apply vacuum to the MAP sensor in 1 inch Hg increments until 15 inches Hg is reached. Each 1 inch Hg should decrease the MAP Sensor parameter by 3-4 kPa. Is the decrease in the MAP Sensor parameter consistent?	-	Go to Step 7	Go to Step 10
7	Apply vacuum with the vacuum pump until 20 inches Hg is reached. Is the MAP Sensor parameter less than the specified value?	34 kPa	Go to Step 8	Go to Step 10
8	Disconnect the vacuum pump from the MAP sensor. Does the MAP Sensor parameter return to the value observed in Step 4?	-	Go to Step 9	Go to Step 20
9	An engine in poor mechanical condition can cause this DTC to set. Inspect for the following conditions: A restricted exhaust system-Refer to Restricted Exhaust . Worn piston rings or valves-Refer to Engine Compression Test . Incorrect cam timing-Refer to Timing Chain, Sprockets, and/or Tensioner Replacement . Did you find and correct the condition?	-	Go to Step 22	Go to Testing for Intermittent Conditions and Poor Connections
10	Test for an intermittent and for a poor connection at the MAP sensor. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 11
11	Disconnect the MAP sensor electrical connector. Observe the MAP Sensor parameter with a scan tool. Is the MAP Sensor parameter less than the specified value?	0.1 V	Go to Step 12	Go to Step 15
12	Turn ON the ignition, with the engine OFF. Connect a test lamp between the 5-volt reference circuit of the MAP sensor at the harness connector and a good ground. Measure the voltage from the 5-volt reference circuit of the MAP sensor to a good ground with a DMM. Is the voltage within the specified range?	4.8-5.2 V	Go to Step 14	Go to Step 13
13	Is the voltage more than the specified value?	5.2 V	Go to Step 16	Go to Step 17
14	IMPORTANT: All electrical components and accessories must be turned OFF. Turn OFF the ignition for 90 seconds to allow the control modules to power down. Measure the resistance from the low reference circuit of the MAP sensor to a good ground with a DMM. Is the resistance more than the specified value?	5 Ω	Go to Step 18	Go to Step 20
15	Test the MAP sensor signal circuit between the PCM and the MAP sensor for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 19
16	Test all branches of the 5-volt reference circuit that is shared with the MAP sensor for a short to voltage. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 19
17	Test the 5-volt reference circuit between the PCM and the MAP sensor for a high resistance. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 19
18	Test the low reference circuit between the PCM and the MAP sensor for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 19
19	Test for shorted terminals and for poor connections at the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs . Did you find and correct the condition?	-	Go to Step 22	Go to Step 21
20	Replace the MAP sensor. Refer to Manifold Absolute Pressure (MAP) Sensor Replacement (TMAP) or Manifold Absolute Pressure (MAP) Sensor Replacement (SCIP) . Did you complete the replacement?	-	Go to Step 22	-
21	Replace the PCM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 22	-
22	Clear the DTCs with a scan tool. Turn OFF the ignition for 90 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the Conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 2	Go to Step 23
23	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List - Vehicle	System OK
