    Symptom Troubleshooting Index These symptoms DO NOT trigger diagnostic trouble codes (DTCs) or cause the malfunction indicator lamp (MIL) to come on. If the MIL is reported on, check for DTCs. If the vehicle has one of these symptoms, do the diagnostic procedure for it, in the sequence listed, until you find the cause.

    Fuel and Emissions Systems System Descriptions Electronic Control System The functions of the fuel and emission control systems are managed by the powertrain control module (PCM). Fail-safe Function When an abnormality occurs in the signal from a sensor, the PCM ignores that signal and assumes a pre-programmed value for that sensor that allows the engine to continue to run.
  • Page 320 Trouble Code consisting of one letter and 4 numbers. Depending on the detected, there is no (DTC) problem, as SAE-defined code (P0xxx) or a Honda-defined output. code (P1xxx) will be output to the tester. Engine Speed The PCM computes engine speed from the signals sent Nearly the same as from the Crankshaft Position (CKP) sensor.
  • Page 321 Fuel and Emissions Systems System Descriptions (cont’d) PCM Data (cont’d) Data Description Operating Value Freeze Data Fuel System Fuel system status is indicated as ‘‘open’’ or ‘‘closed’’. At idle speed: closed Status Closed: Based on the HO2S output, the PCM determines the air/fuel ratio and controls the amount of injected fuel.

  • Page 631: System Description

    Automatic Transmission System Description General Operation The automatic transmission is a combination of a 3-element torque converter and triple-shaft electronically controlled unit which provides 4 speeds forward and 1 reverse. The entire unit is positioned in line with the engine. Torque Converter, Gears, and Clutches The torque converter consists of a pump, turbine, and stator assembly in a single unit.

Position Description P: PARK Front wheels locked; park pawl engaged with park gear on countershaft. All clutches are released.
  • Page 633 Automatic Transmission System Description (cont’d) Clutches The 4-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears. When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs and steel plates together, locking them so they don’t slip. Power is then transmitted through the engaged clutch pack to its hub-mounted gear.

  • Page 644 Shift Control Shifting is related to engine torque through the solenoid valves, which are controlled by the PCM. The PCM instantly determines which gear should be selected by various signals sent from sensors, and actuates the shift solenoid valves A, B, and C to control shifting. Also, a grade logic control system has been adopted to control shifting in the D4 and D3 positions while the vehicle is ascending or descending a slope, or reducing speed.
  • Page 645 Automatic Transmission System Description (cont’d) Electronic Control System (cont’d) Grade Logic Control System How it works: The PCM compares actual driving conditions with memorized driving conditions, based on the input from the countershaft speed sensor, the throttle position sensor, the engine coolant temperature sensor, the brake pedal position switch signal, and the shift lever position signal, to control shifting while the vehicle is ascending or descending a slope, or reducing speed.
  • Page 646 Grade Logic Control: Ascending Control When the PCM determines that the vehicle is climbing a hill in the D4 and D3 positions, the system extends the engagement area of 2nd gear and 3rd gear to prevent the transmission from frequently shifting between 2nd and 3rd gears, and between 3rd and 4th gears, so the vehicle can run smooth and have more power when needed.

  • Page 875: System Description

    Automatic Transmission System Description General Operation The automatic transmission is a combination of a 3-element torque converter and triple-shaft electronically controlled unit which provides 5 speeds forward and 1 reverse. The entire unit is positioned in line with the engine. Torque Converter, Gears, and Clutches The torque converter consists of a pump, turbine, and stator assembly in a single unit.
  • Page 876 Gear Selection The shift lever has seven positions; P: PARK, R: REVERSE, N: NEUTRAL, D: 1st through 5th gear ranges, D3: 1st through 3rd gear ranges, 2: 2nd gear, 1: 1st gear. Position Description P: PARK Front wheels locked; park pawl engaged with park gear on countershaft. All clutches are released.
  • Page 877 Automatic Transmission System Description (cont’d) Clutches The 5-speed automatic transmission uses hydraulically-actuated clutches to engage or disengage the transmission gears. When hydraulic pressure is introduced into the clutch drum, the clutch piston moves. This presses the friction discs and steel plates together, locking them so they don’t slip. Power is then transmitted through the engaged clutch pack to its hub-mounted gear.
