7.2.2 Installation Instructions
1. Lubricate the o-ring seal on the MAP sensor to ensure it is not damaged during installation.
2. Thread the MAP sensor into the appropriate location on or near the intake manifold using the 5mm thru-
holes and the selected mounting hardware.
• Do not over torque the assembly down and ensure that the barb fitting is not damaged during
installation and is free from obstruction.
3. If the sensor is remote mounted, install the barb fitting on the intake manifold which should a 6.4mm [0.25
in] barb fitting.
• Install a section of hose from the intake manifold to the MAP sensor.
• Ensure the vacuum hose is positioned and cut to the appropriate length to avoid kinks or low points in
the line.
• Avoid routing the vacuum hose next to high temperature components such as turbo-chargers and
exhaust systems.
7.3 Exhaust Oxygen Sensor
The engine exhaust oxygen level sensor is used to determine whether or not the engine is running lean or rich
and to facilitate the closed loop feedback from the control system. A stoichiometric oxygen sensor (narrow-band)
with an output signal of 0 to 1V is used with the AFR.
An internal heater element (12V only) allows the sensor to reach its activation temperature quickly for accurate
measurements. Depending on the configuration selected you will have one (pre-catalytic converter) or two (pre-
and post-catalytic converter) sensors. A representation of the GAC narrow-band oxygen sensors are shown in
the following figure.
