Fuel and Emissions System Description - Supplement
ECM/PCM Data
You can retrieve data from the ECM/PCM by connecting the scan tool or the Honda PGM Tester to the Data Link Connector (DLC). The items listed in the table below conform to SAE recommended practice. The Honda PGM Tester also reads data beyond that recommended by SAE so that this data may help you find the causes of intermittent problems.
NOTE:
- The ‘‘operating values'' listed are approximate and may vary depending on the environment and the individual vehicle.
- Unless noted otherwise, ‘‘at idle speed'' means idling with the engine completely warmed up, A/T in Park or neutral, M/T in neutral position, and the A/C and all accessories turned off.
| Data | Description | Operating Value | Freeze Data |
|---|---|---|---|
| Diagnostic Trouble Code (DTC) | If the ECM/PCM detects a problem, it will store it as a code consisting of one letter and four numbers. Depending on the problem, an SAE-defined code (P0xxx) or a Honda-defined code (P1xxx) will be output to the tester. | If no problem is detected, there is no output. | YES |
| Engine Speed | The ECM/PCM computes engine speed from the signals sent from the Crankshaft Position (CKP) sensor. This data is used for determining the time and amount of injected fuel. | Nearly the same as tachometer indication At idle speed: 750±50 rpm (min-1) | YES |
| Vehicle Speed | The ECM/PCM converts pulse signals from the Vehicle Speed Sensor (VSS). | Nearly the same as speedometer indication | YES |
| Manifold Absolute Pressure (MAP) | The absolute pressure caused in the intake manifold by engine load and speed. | With engine stopped: Nearly the same as atmospheric pressure At idle speed: about 20-34 kPa (150-260 mmHg, 6-10 in. Hg), 0.7-1.1 V | YES |
| Engine Coolant Temperature (ECT) | The ECT sensor converts coolant temperature into voltage and signals the ECM/PCM. The sensor is a thermistor whose internal resistance changes with coolant temperature. The ECM/PCM uses the voltage signals from the ECT sensor to determine the amount of injected fuel. | With cold engine: Same as ambient temperature and IAT With engine warmed up: about 80-100°C (176-212°F), 0.5-0.8 V | YES |
| Heated Oxygen Sensor (HO2S) | The HO2S detects the oxygen content in the exhaust gas and sends voltage signals to the ECM/PCM. Based on these signals, the ECM/PCM controls the air fuel ratio. When the oxygen content is high (that is, when the ratio is leaner than the stoichiometric ratio), the voltage signal is lower. When the oxygen content is low (that is, when the radio is richer than the stoichiometric ratio), the voltage signal is higher. | 0.0-1.25 V At idle speed: about 0.1-0.9 V | NO |
| Data | Description | Operating Value | Freeze Data |
|---|---|---|---|
| Fuel System Status | Fuel system status is indicated as ‘‘open'' or ‘‘closed''. Closed: Based on the HO2S output, the ECM/PCM determines the air/fuel ratio and controls the amount of injected fuel. Open: ignoring the HO2S output, the ECM/PCM refers to signals from the Throttle Position (TP), Manifold Absolute Pressure (MAP), Intake Air Temperature (IAT), Barometric Pressure (BARO) and Engine Coolant Temperature (ECT) sensors to control the amount of injected fuel. | At idle speed: closed | YES |
| Short Term Fuel Trim | The air/fuel ratio correction coefficient for correcting the amount of injected fuel when the Fuel System Status is ‘‘closed.'' When the ratio is leaner than the stoichiometric ratio, the ECM/PCM increases short term fuel trim gradually, and the amount of injected fuel increases. The air/fuel ratio gradually gets richer, causing a lower oxygen content in the exhaust gas. Consequently, the short term fuel trim is lowered, and the ECM/PCM reduces the amount of injected fuel. This cycle keeps the air/fuel ratio close to the stoichiometric ratio when in closed loop status. | 0.70-1.47 | YES |
| Long Term Fuel Trim | Long term fuel trim is computed from short term fuel trim and indicates changes occurring in the fuel supply system over a long period. If long term fuel trim is higher than 1.00, the amount of injected fuel must be increased. If it is lower than 1.00, the amount of injected fuel must be reduced. | 0.72-1.35 | YES |
| Intake Air Temperature (IAT) | The IAT sensor converts intake air temperature into voltage and signals the ECM/PCM. When intake air temperature is low, the internal resistance of the sensor increases, and the voltage signal is higher. | With cold engine: Same as ambient temperature and ECT | YES |
| Throttle Position | Based on the accelerator pedal position, the opening angle of the throttle valve is indicated. | At idle speed: about 10 %, 0.5 V | YES |
| Ignition Timing | Ignition timing is the ignition advance angle set by the ECM/PCM. The ECM/PCM matches ignition timing to the driving conditions. | At idle speed: 8° ± 5° BTDC when the SCS service signal line is jumped with the Honda PGM tester | NO |
| Caluculated Load Valve (CLV) | CLV is the engine load calculated from the MAP data. | At idle speed: 12-34 % At 2,500 rpm (min-1) with no load: 15-25 % | YES |
