1. 2. 3. 4. 5. 6. 7. 8. DISCONNECT NEGATIVE(-) BATTERY CABLE. Disconnect air temperature sensor connector from intake hose assembly. Using a 8mm socket, loosen hose clamps on intake hose assembly and air box on top of throttle body. Using a 10mm socket, remove bolt mounting air box assembly on top of throttle body. Remove air box assembly. Disconnect vacuum lines and electrical connectors from throttle body. Using 10mm socket, remove (4) bolts mounting throttle body to intake manifold. Remove throttle body from intake manifold. Clean sealing surface of throttle body and intake manifold being careful not to damage factory o-ring seal. * Optional: Included in the hardware pack is (1) 3/16 vacuum line fitting; this may be used for a vacuum gauge. If PowerPorts are utilized, install necessary fittings before installing spacer on vehicle. Other 1/16 NPT fittings may be installed such as power adders. Refer to PowerPort section. 9. Install power plate by placing the part number facing the throttle body with one supplied gasket on top of the power plate. * Note: Gaskets and spacer must be placed in correct orientation to line up with factory bolt holes.) (Ref. A) 10. Install the (4) supplied bolts and washers in throttle body; tighten evenly. DO NOT OVER TIGHTEN. (Ref. B) 11. Reconnect all electrical connectors and vacuum lines to throttle body. 12. Using 3/4 inch long spacer, bolt, and washer provided, reinstall the air box assembly. (Ref. C) 13. Reinstall intake tube and tighten hose clamps. 14. Reconnect air temperature sensor connector to intake tube. 15. Inspect & Test throttle linkage for full Open & Closed travel before driving. Cables may require adjustment. Please refer to service manual for proper adjustment. 16. Reconnect negative battery cable. Enjoy!

Wiring Diagram

CIRCUIT DESCRIPTION UART serial data communication is a method by which components or modules can transfer information to each other. The serial data communication circuit is connected to four components or modules: the Powertrain Control Module (PCM), Diagnostic Energy Reserve Module (DERM), Electronic Brake Control Module (EBCM) , and the electronic Instrument Panel Cluster (IPC). The IPC is the master of this network and sends out updated information and requests updated information from the other modules through the serial data circuit. Each module in turn responds back to the IPC with updated information used by the IPC. The PCM communicates with the EBCM through the IPC over the serial data circuit. If any of the modules cannot respond to each other; a DTC is set in each applicable module. CONDITIONS FOR SETTING THE DTC
PCM does not receive 25 valid responses from the IPC.
System voltage is greater than 6.8 volts. Above conditions are met for 10 seconds. ACTION TAKEN WHEN THE DTC SETS

1 of 2

The PCM will record operating conditions at the time the diagnostic fails. This information will be stored in the Failure Records buffer. A history DTC is stored. IPC illuminates the telltales the PCM controls through the serial data line: Low coolant low oil level Volts CONDITIONS FOR CLEARING THE MIL/DTC A history DTC will clear after 40 consecutive warm up cycles without a fault. A scan tool can clear the MIL/DTC(s). DIAGNOSTIC AIDS Move the PCM and IPC connectors while watching the IPC to see if serial data is lost. When serial data is lost, the IPC telltales are illuminated. This is a good indication that serial data is lost to the IPC. An intermittent problem may be caused by electrical interference on the ground circuit of the IPC, a poor connection, rubbed through wire insulation, or a wire that is broken inside the insulation. Any circuitry, that is suspected as causing the intermittent complaint, should be thoroughly checked for the following conditions: Backed out terminals Improper mating Broken locks Improperly formed Damaged terminals Poor terminal to wire connection Install an additional ground wire from the IPC to the negative side of the battery if electrical interference is suspected. Refer to Diagrams for additional diagnostic information. TEST DESCRIPTION Number(s) below refer to the step number(s) on the Diagnostic Table. 1. The Powertrain OBD System Check prompts the technician to complete some basic checks and store the freeze frame and failure records data on the scan tool if applicable. This creates an electronic copy of the data taken when the malfunction occurred. The information is then stored on the scan tool for later reference. 2. When the Coolant Level telltale stays illuminated, serial data is lost to the IPC. If the engine starts and continues to run, an optional test is to observe the following telltales and gauges for proper operation. If all of these telltales illuminate or the gauges are not operating properly, serial data is lost to the IPC: Oil Pressure Telltale Voltage Telltale Tachometer (If Equipped) Temperature Gauge (If Equipped) 3. If the scan tool cannot read the serial data from the IPC, be sure that the scan tool is working properly on another vehicle. 4. The open in the circuit can be narrowed down by determining which modules can communicate with the scan tool. 5. A short in the UART serial data circuit will cause all of the IPC telltales in step 2 to illuminate plus the additional telltales controlled by the other modules on the circuit. 7. If the scan tool can communicate normally with the IPC once the PCM electrical connectors are disconnected, then the PCM is causing the short on the UART serial data circuit. 8. The replacement PCM must be programmed and the crankshaft position system variation procedure must be preformed. Refer to the latest Tech line procedure for PCM reprogramming and also refer to CKP System Variation Learn Procedure for the Crankshaft Position System Variation Procedure. 10. If no malfunctions have been found at this point and no additional DTCs were set, refer to Diagnostic Aids for additional checks and information.
