Title: 1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P0107,P0108; Manifold Absolute Pressure / Barometric
Pressure Circuit Low Input; 2015 MY Tundra [08/2014 - ]
DTC
P0107
Manifold Absolute Pressure / Barometric Pressure Circuit Low Input
DTC
P0108
Manifold Absolute Pressure / Barometric Pressure Circuit High Input
DESCRIPTION
By a built-in sensor unit, the manifold absolute pressure sensor detects the intake manifold pressure as a
voltage.
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P0107
The manifold absolute pressure sensor voltage is
below 0.5 V for 0.5 seconds.
(1 trip detection logic)
Open or short in manifold absolute
pressure sensor circuit
Manifold absolute pressure sensor
ECM
P0108
The manifold absolute pressure sensor voltage is
higher than 4.5 V for 0.5 seconds.

MONITOR DESCRIPTION
The ECM monitors the sensor voltage and uses this value to calculate the manifold absolute pressure. When the
sensor output voltage deviates from the normal operating range, the ECM interprets this as a malfunction in the
manifold pressure sensor and sets a DTC.
Example:
When the sensor output voltage remains less than 0.5 V, or more than 4.5 V for more than 0.5 seconds, the ECM
sets a DTC.
If the malfunction is not repaired successfully, a DTC is set 0.5 seconds after the engine is next started.

CONFIRMATION DRIVING PATTERN
Connect the Techstream to the DLC3.
1.
Turn the ignition switch to ON and turn the Techstream on.
2.
Clear DTCs (even if no DTCs are stored, perform the clear DTC operation).
3.
Turn the ignition switch off and wait for at least 30 seconds.
4.
Turn the ignition switch to ON and turn the Techstream on.
5.
Start the engine.
6.
Idle the engine for 5 seconds [A].
7.
Enter the following menus: Powertrain / Engine and ECT / Trouble Codes [B].
8.
Read the pending DTCs.
HINT:
If a pending DTC is output, the system is malfunctioning.
If a pending DTC is not output, perform the following procedure.
9.
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
10.
Input the DTC: P0107 or P0108.
11.
Check the DTC judgment result.

Perform driving pattern after confirming DTC enabling conditions
N/A
Unable to perform DTC judgment
HINT:
If the judgment result shows INCOMPLETE or N/A, perform steps [A] through [B] again.
12.
If no pending DTC is output, perform a universal trip and check for permanent DTCs
.
HINT:
If a permanent DTC is output, the system is malfunctioning.
If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE
HINT:
If DTCs relating to different systems are stored and they share terminal E2 as their ground, check this
ground circuit first.
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information
as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help
determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio
was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1.
READ VALUE USING TECHSTREAM (MANIFOLD ABSOLUTE PRESSURE)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Data List / MAP.
(e) Read the MAP value.
OK:
Same value as the actual atmospheric pressure.
HINT:
Standard atmospheric pressure is 101 kPa. For every 100 m increase in altitude, pressure drops by 1 kPa.
Varies by weather (high atmospheric pressure, low atmospheric pressure).
Also, check "Atmosphere Pressure" in the Data List.
NG
GO TO STEP 2
OK
CHECK FOR INTERMITTENT PROBLEMS
2.
CHECK MANIFOLD ABSOLUTE PRESSURE SENSOR (TERMINAL VOLTAGE)
