3.
REPLACE CANISTER PUMP MODULE
(a) Replace the canister pump module
.
NOTICE:
When replacing canister pump module, check the canister pump module interior, canister interior and
related pipes for water, fuel and other liquids. If liquids are present, check for disconnections and/or
cracks in the following: 1) the pipe from the air inlet port to the canister pump module; 2) the canister
filter; and 3) the fuel tank vent hose. If liquids are present in canister interior, replace canister and
canister pump module together (replace canister assembly).
Check for filter blockage in the canister assembly. If the charcoal filter inside the canister assembly is
clogged, replace canister and canister pump module together (replace canister assembly).
Check for filter blockage in the canister filter. If the canister filter has blockages, replace the canister
filter.

6.
CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON and turn the Techstream on.
(c) Enter the following menus: Powertrain / Engine and ECT / Data List / Vapor Pressure Pump, Air
pump pressure (absolute) and Air Pump2 Pressure (Absolute).
(d) Confirm that the difference between Vapor Pressure Pump and Air pump pressure (Absolute),
and the difference between Vapor Pressure Pump and Air Pump2 Pressure (Absolute) are 3.5
kPa (+/- 26.25 mmHg) or less.

(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
changes between the protrusion on the teeth and MRE. The change affects the magnetic field and results in
crankshaft position sensor generates 34 signals at every engine 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.
