2 Bar Sensor (Part No. 886 3189)
(-100kPa to 100kPa) Turbo or Supercharged
Engines up to 100kPa boost
(15 psi , 1 atmosphere)
3 Bar Sensor (Part No. 749 3169)
(-100kPa to 200kPa) Turbo or Supercharged
Engines up to 200kPa boost
(30 Psi, 2 atmospheres)
Note: M ake sure you have the correct MAP sensor for your engine. The first
three digits of the part number are stamped on the sensor housing.
If the engine is running in Throttle Position mode, a 1 Bar MAP sensor (left
open to atmosphere) is used to measure the barometric pressure.
If the engine is running in Manifold Pressure Mode, at least one M AP sensor
must be used. The first MAP sensor must be connected to the M AP Input plug
on the wiring loom and provides an indication of the engine load.
The second MAP sensor (1 Bar MAP sensor left open to atmosphere) is used
to measure barometric pressure can be fitted. It connects to the Spare Input
plug near the Main Connector.
Mounting
The MAP sensor is usually mounted high on the engine bay firewall or inner guard using two
screws and with the hose nipple facing outwards. Connect the sensor to the inlet manifold via
a short length of vacuum hose and fasten with either hose clamps or nylon cable ties. Connect
the sensor to the main wiring harness using the appropriate plug. (For 1 Bar sensors the plug
is green, for 2 and 3 Bar sensors the plug is orange). Avoid mounting the sensor below the
level of the fuel injectors, because fuel may collect in the vacuum hose and run down into the
sensor. The sensor assembly is weatherproof but it is good practice to mount the sensor in a
protected p osition away from moisture and heat.
1.3.2. Coolant Temperature Sensor
The coolant temp erature is used to determine the fuel mixture corrections requir ed when not
at operating temp erature.
The coolant temp erature sensor has a solid brass temp erature sensing tip. Refer to the diagram
below for technical details of the sensor. The coolant sensor supplied is an industry standard
component and some engines may already have provision for this type of sensor.
The coolant temperature sensor is designed to screw into a threaded hole and protrude into the
engine coolant stream. For air-cooled engines, the sensor can be embedded directly into the
engine block or used to sense oil temperature.
Locate a suitable p osition on the engine which will allow the hole and thread to be mach ined,
