Fuel Injection Sensors
Electronic fuel
management systems all rely on a variety of inputs from sensors to calculate
the engine's requirements for fuel or timing while it is running. MSD
offers a variety of sensors for custom EFI installations.
Coolant
or Oil Temperature Sensor
 Your
engine's coolant temperature is one of the primary inputs for EFI management
systems. This sensor produces a variable resistance from -40°F - 302°F
ranging from 100K-50 ohms. It threads into a 3/8" NPT hole and is supplied
with a matching 2-Pin connector, seals and terminals for reliable, positive
locking connections.

Intake
Air Temperature Sensor
 Installing
this sensor in your air cleaner assembly or intake will relay the temperature
of the air entering your engine. This information assists the ECU as
it tries to produce an optimum air-to-fuel ratio for the engine. It
is supplied with matching 2-pin connector and produces a variable resistance
from 100K-50 ohms. It mounts in a 3/8" NPT hole.

Heated
Oxygen Sensor
 All EFI management
systems monitor the oxygen content of the exhaust gases to calculate
the fuel mixture. MSD's Heated Oxygen Sensor is a fast responding sensor
to reliably deliver reference information to the ECU. This sensor uses
an internal heat supply to remain at a constant 1,300°F for less variance
in producing important signals. This is also a benefit in that the sensor
doesn't have to warm up and is active even when the engine is first
started. The sensor is a direct replacement for factory mounting bosses.

NOTE: For custom installations, Mounting Boss PN 2335 is required. |
Oxygen
Sensor Mounting Boss
 To
install MSD's Heated Oxygen Sensor on custom applications you will need
this Mounting Boss. A chromate coated plug to seal the boss is also
supplied.

Manifold
Absolute Pressure Sensor
 The pressure inside
the intake manifold is an extremely important input to the ECU. This
Sensor will respond to changes in manifold pressures and relay the information
to the ECU in the form of a voltage signal ranging from about 1 volt
to 5 volts. Several different versions are available for normal aspirated
and engines with blowers.
MAP Sensor, 1-Bar, (normally aspirated applications) (PN 2311)
MAP Sensor, 2-Bar, (for
blown or turbo applications up to 20 lbs of boost) (PN 2312)
Compact Model, (PN 23121)
MAP Sensor, 3-Bar, for
blown or turbo applications up to 30 lbs of boost (PN 2313)
Compact Model, (PN 23131) |
