Fault code is P0120. Tests/Procedures: 1. Connect scan tool and monitor voltages of pedal sensor B37. Signal 1 (Accelerator pedal position: Idle speed):[0.2...0.5] V Signal 2 (Accelerator pedal position: Idle speed):[0.1...0.5] V Signal 1 (Accelerator pedal position:Kickdown):[4.3...4.8] V Signal 2 (Accelerator pedal position:Kickdown):[2.1...2.5] V 2. If voltages are out of specification verify correct reference voltage to sensor by measuring between pins 6 (Black/White wire) and pin 1 (Blue/Grey wire) on pedal sensor connector. Voltage needs to be between 4.75 and 5.25 volts. 3. Test throttle body voltages with scan tool. Potentiometer #2 signal voltage ignition on, accelerator pedal position CTP 0.3-0.9 VDC, WOT > CTP value Potentiometer #1 signal voltage Ignition on, accelerator pedal position CTP 4.0-4.6 VDC, WOT < CTP value.… Read More

1998 Acura 3.5RL ENGINE PERFORMANCE Basic Diagnostic Procedures

Download 1. Remove fuel tank filler cap. Listen for fuel pump operation noise at fuel tank filler. Fuel pump should operate for 2 seconds after ignition switch is turned on. If fuel pump operates as specified, fuel pump is okay. If fuel pump does not operate as specified, go to next step. 2. Turn ignition switch off. Remove rear seat or trunk floor to gain access to fuel pump connector. Disconnect fuel pump connector. Disconnect PGM-FI main relay connector. Connect a fused jumper wire between PGM-FI main relay connector FUEL PUMP fuse side terminal and fuel pump side terminal. See L – WIRING DIAGRAMS article. 3. Turn ignition switch on. Using a voltmeter connected to ground, check for battery voltage at fuel pump harness side connector. See L – WIRING DIAGRAMS article. If battery voltage is not present, check harness between fuel pump and FUEL PUMP fuse. Repair as necessary. If battery voltage is present, check fuel pump ground.… Read More
