Engine Sensors & Tools
Sensors
Manifold Absolute Pressure (MAP) Sensor
The MAP sensor reads the vacuum or pressure in the manifold. This sensor provides key information for all Electromotive speed density based fuel injection systems, and is also used with the XDi vacuum advance and boost retard. The sensor is available in 3 varieties for normally aspirated or boosted engines.
| 1 bar MAP sensor (for normally aspirated engines) |
71110 |
| 2 bar MAP sensor (for forced induction to 14.5 boost) |
71120 |
| 3 bar MAP sensor (for forced induction to 29.0 boost) |
71130 |
Throttle Position Sensor (TPS)
The TPS is a potentiometer attached to the throttle shaft. A five volt signal is supplied to the sensor, and a variable voltage is returned to the TEC. The voltage increases as the throttle is opened. Four varieties of sensors are available from Electromotive. The TPS sensors of many late model vehicles can be used with the TEC products.

Coolant Temperature Sensor (CLT)
The CLT sensor measures the temperature of the coolant in the engine block. This negative temperature coefficient resistor provides a 2.8k ohm resistance at 70 degree F. Used by the TEC products. Thread is 3/8" NPT.
Manifold Air Temperature (MAT)
The MAT measures incoming air temperature for the TEC speed density products only. The sensor screws into a 3/8" NPT threaded port which should locate the tip in the incoming air stream, but away from fuel.
Knock Sensor
The TEC and XDi2 products make use of a piezoelectric sensor that is especially tuned to pickup engine vibrations created by knock (also called detonation or ping). The sensor has a 3/8" NPT thread for attachment to the engine block or cylinder head. Above approximately 5000 rpm, however, this knock may be masked by mechanical noise; Electromotive calibration software allows the user to program an upper rpm limit to disable the sensor.

Exhaust Gas Oxygen (EGO) Sensor
The EGO sensor is an electrochemical cell used to measure the oxygen content of an engine's exhaust. In closed loop operation, TEC uses this signal to monitor and adjust fuel mixture. A heated sensor should be used with TEC systems from Electromotive. On a note, Electromotive's TEC was the first fuel injection system to use a heated EGO sensor to operate closed loop anywhere in the range of the Oxygen sensor almost 20 years ago.

Actuators
Idle Air Control (IAC) Motor
The IAC motor is a 4 wire stepper motor completely under TEC control. The motor drives a pintle valve to control the bypassing of air around the throttle plates. This air control is used to stabilize engine idle speed and to compensate for occasional additional loads, such as an air conditioning compressor. Two GM style motors are available from Electromotive. The screw-in type has M20 x 1.5 threads with a square, 4 pin connector. The o-ring style, bolt-on motor uses an in-line 4 pin connector. If your throttle body does not have provisions for the GM style motor, Electromotive offers two billet aluminum IAC motor bodies that accept the threaded motor. One body provides two hose barbs so air can be plumbed with hoses to both sides of your air door. The other body is to be wrapped in an air filter and connected downstream of the throttle with one hose.

General Purpose Output Solenoid
The GPO output is capable of pulse width modulating a solenoid valve. The valve can then regulate the flow pressure or vacuum. Typically these valves are used for proportional EGR, turbo waste gain control or canister purge. The GPO output is standard on Electromotive systems so equipped. The two 1/8" NPT hose nipples shown are not included. Various orifice sizes are available. Contact Electromotive for help with your application.
