Title: 1UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P1340,P1342,P1343; Camshaft Position Sensor "A"
(Bank 1 Sensor 2); 2015 MY Tundra [08/2014 - ]
DTC
P1340
Camshaft Position Sensor "A" (Bank 1 Sensor 2)
DTC
P1342
Camshaft Position Sensor "A" Low Input (MRE)
DTC
P1343
Camshaft Position Sensor "A" High Input (MRE)
DESCRIPTION
between the protrusion on the gear and the MRE changes. The change affects the magnetic field and results in
generates 34 signals per crankshaft revolution. The ECM detects the standard crankshaft angle based on the G
signal, and the actual crankshaft angle and engine speed by the NE signal.
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P1340
No camshaft position sensor signal to ECM during cranking
(2 trip detection logic)
Open or short in camshaft
position sensor circuit
Camshaft position sensor
Camshaft timing plate LH
ECM
No camshaft position sensor signal to ECM with engine
speed 600 rpm or more (1 trip detection logic)
P1342
(1 trip detection logic)
P1343
(1 trip detection logic)
MONITOR DESCRIPTION
the sensor output voltage remains below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a
DTC.

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 [A].
5.
Start the engine.
6.
Idle the engine for 10 seconds or more.
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.

WIRING DIAGRAM
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the Techstream. Freeze frame data records the engine conditions when
malfunctions are detected. 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.
