Introduction:
A new electronic transducer module is being installed in the above truck engines. The new electronic transducer module contains only a boost sensor. The former electronic transducer module contained a boost sensor and an oil pressure sensor. After installation, the new electronic transducer module will no longer provide an oil pressure signal to the Electronic Control Module (ECM).The new configuration requires a remote mount oil sensor (and wiring kit) be installed. The remote mount oil kit may or may not already be installed on the engine.Adaptability:
The new 132-4363 Electronic Transducer Module (with an oil pressure sensor kit) is a direct replacement for the former 3E-8540 Electronic Transducer Module and the remanufactured OR-6471 Electronic Transducer Module. Both of the former electronic transducer modules have been canceled.The new 132-4363 Electronic Transducer Module is adaptable to the above truck engines.Reason For Change:
When installed, the new 132-4363 Electronic Transducer Module will no longer contain the oil pressure sensor. This will make the system more reliable.If a Remote Mount Oil Sensor Is Already Installed

When replacing the electronic transducer module with the new 132-4363 Electronic Transducer Module, determine if the engine has a remote mount oil pressure sensor. If it is already installed:* Note and record which wires were pulled from the connector P5 and the position they were installed on the remote mount oil sensor harness.* Note which wires from the remote mount oil sensor harness were installed in the connector P5. Again, note the pin locations.* Replace the electronic transducer module with the new 132-4363 Electronic Transducer Module.* See Illustration 1 for the 3406B and Illustration 2 for the 3406C Remote Oil Sensor Wiring Diagram.If A Remote Mount Oil Pressure Sensor Is Not Installed
* Install a 118-6256 or 122-1649 Oil Pressure Sensor Kit in order to use the new 132-4363 Electronic Transducer Module. See the chart to determine which oil pressure sensor kit to use. Installation instructions are provided in each oil pressure sensor kit.
