Atomic TBI Throttle Position Sensor Module
PN 2939
Parts Included:
1 - TPS Module 1 - Parts Bag
OVERVIEW
The Atomic TBI Throttle Position Sensor Module is designed for use with the MSD Atomic Throttle
Body Fuel Injection system. It connects inline to the Atomic TBI communication network and provides
a common 0-5 volt throttle position output signal that is required for the operation of an electronic
overdrive transmission or other accessory.
CARB Compliant Atomic TBI Installation: The Atomic TBI system has been granted Executive Order
number D-722 which deems it legal to install on 1987 and older GM passenger vehicles and trucks
that were originally equipped with a carburetor and V8 engine. During a CARB Compliant installation,
the factory ECU remains in place to operate the ignition timing and AIR Pump system. In order for
the OE systems to function properly, a TPS signal is required. The outputs of the TPS Module will
provide the correct signals for the factory ECU and is required during any CARB compliant Atomic
TBI installation (see Figure 3).
The Atomic TPS Module has two output wires that must be connected:
• Yellow – 0-5 volt TPS signal
• Black – Ground reference
