Description
Genuine Bosch 3 Bar T-MAP (Temperature Manifold Air Pressure) Sensor with CNC Machined Aluminium Weld-on Boss & 4-pin Connector Kit.
This T-MAP combines a 3 Bar MAP sensor and an intake air temperature sensor all into one compact unit.
Suitable for turbocharged or supercharged engines running up to 2 Bar (29 PSI) of boost pressure.
The sensor comes with an aluminium weld-on boss which can be welded to an intake manifold (plenum). The composite sensor body resists heat soak allowing the sensor to be mounted directly in the plenum without adversely effecting the IAT measurement . Ideally, the sensor should be mounted on the top face of the plenum which reduces the risk of condensation accumulating on the sensor as well as radiant heat transfer from the cylinder head. This sensor is particularly well suited for custom intake manifolds that have no provision for a MAP sensor but can also be welded to a factory intake manifold if needed.
Pinout:
Pin 1 = Ground
Pin 2 = IAT Signal
Pin 3 = 5v Power Supply
Pin 4 = MAP Signal
Calibration:
MAP sensor linear calibration – 0.5V = 27Kpa absolute, 4.5v = 289Kpa absolute (maximum is 4.83V = 327Kpa)
Intake air temperature sensor = select ‘Bosch NTC’ calibration on Link G4 and G4 ECUs
