NOTE: System on naturally aspirated vehicle shown, system on supercharger vehicle similar. 1 EVAP canister 2 Vapor pipe (filler head communication) - fuel tank to filler pipe 3 DMTL (diagnostic module - tank leakage) filter 4 Atmospheric vent pipe - DMTL pump to filter 5 DMTL pump 6 Vapor pipe - EVAP canister to EVAP canister purge valve 7 Vapor pipe - fuel tank to EVAP canister 8 EVAP canister purge valve

is routed from the EVAP canister purge valve to the inlet of the intake manifold (naturally aspirated vehicles) or the supercharger (supercharged vehicles). The EVAP canister purge valve is controlled by the ECM and is operated when engine operating conditions are correct to allow purging of the EVAP canister. The EVAP canister purge valve is a solenoid operated valve which is closed when de-energized.

A vapor pipe, which runs parallel with the fuel delivery line under the LH side of the vehicle, connects the EVAP canister purge valve to the EVAP canister.
The EVAP canister purge valve is operated at 10 Hz by a PWM (pulse width modulation) signal from the ECM. At this high frequency, the pulses of fuel vapor flow into the intake manifold/supercharger in an almost continuous flow. The valve operates
between 7% and 100% duty or mark space ratio (percentage open time).

Atmospheric pressure is higher than the pressure at the inlet of the intake manifold/supercharger under all throttle settings
and engine running conditions. It is this pressure differential that causes air to flow through the EVAP system to the engine. EVAP CANISTER PURGE VALVE

MANIFOLD ABSOLUTE PRESSURE SENSOR


The MAP sensor allows the ECM to calculate the load on the engine, which is used in the calculation of fuel injection time.
The MAP sensor is installed in the air inlet of the SC (supercharger). The sensor is secured with a single screw and sealed with an O-ring. A three pin electrical connector provides the interface with the engine harness.

If the MAP sensor fails, the ECM adopts a default value of 1 bar (14.5 lbf/in.2
). With a failed MAP sensor, the engine will suffer from poor starting, rough running and poor driveability.
MASS AIR FLOW AND TEMPERATURE SENSORS



The MAFT sensors allow the ECM to measure the mass and the temperature of the air flow into the engine. The mass air flow is measured with a hot film element in the sensor. The temperature of the air flow is measured with a NTC thermistor in the sensor. The mass air flow is used to determine the fuel quantity to be injected in order to maintain the stoichiometric air/fuel
mixture required for correct operation of the engine and the catalytic converters.

There are two MAFT sensors installed, one in each air cleaner outlet duct. Each MAFT sensor is secured with two screws and sealed with an O-ring. On each MAFT sensor, a five pin electrical connector provides the interface with the engine harness.
If the hot film element signal fails the ECM invokes a software backup strategy to calculate the mass air flow from other inputs. Closed loop fuel control, closed loop idle speed control and evaporative emissions control are discontinued. The engine
will suffer from poor starting, poor throttle response and, if the failure occurs while driving, the engine speed may dip before
recovering.
If the NTC thermistor signal fails the ECM adopts a default value of 25 °C (77 °F) for the intake air temperature.
