1.11 Pressure- MAP-sensor AEB025
Specifications:
Name: AEB025
LPG type approval N°: E3 67R-01 0216
The four wire connection (with 4way superseal connector) is for :
- +5V feeding
- Ground
- Vacuum signal (0 – 2,5 bar)
- Pressure signal (0-4,5 bar) Class2
This component is used in bifuel LPG vehicles. It measures
pressure after pressure regulator and vacuum at manifold.
Pressure signals are changed in electrical signals in the way
that they can be analyzed by ECU. The AEB 025 Double Map sensor is suitable to manage two different pressure
signals: one from manifold (V) and one from injector rail gas pressure.
1.11.1 MAP-sensor installation instructions:
•
Check whether an original unused connection point is available.
If no such point is available;
•
Detach the inlet manifold, ensuring that the gasket is not damaged and take note of any components and
connections.
•
Determine the position of the vacuum connection that will be made in accordance with the specific installation
instructions.
•
If not explicitly specified in the installation instructions, personally determine an easily accessible connection
point, preferably just behind the throttle valve.
•
First determine the centre before drilling the hole.
•
Apply some grease around the drill bit to prevent the shavings from flying around and drill a 4.8-mm hole in
case of an aluminium manifold and a 4.5-hole in case of a plastic manifold. While drilling, it is important that the
drill is held at a right angle to the surface.
•
Tapping screw thread M6x1.
•
Carefully remove all drill shavings.
•
Install the vacuum connecting nipple using sealant/adhesive fluid.
•
Only install the inlet manifold once the nozzles have been mounted.
•
Reinstall the inlet manifold, with a new gasket if required, and connect all detached components again.
