Abbreviations, Definitions
| SEC. AIR INJ. | = | Extra control valve for air injection in cold running phase. (0 to 10 sec after engine start) |
|---|---|---|
| COOLANT TEMP. | = | Coolant temperature |
| INTAKE AIR TEMP. | = | Intake air temperature |
| MAP SENSOR | = | Intake manifold absolute pressure sensor |
| BAROMETER SENSOR | = | Barometer sensor; air pressure sensor. This sensor is not really present, rather the "inlet manifold absolute pressure sensor" is used to measure the value when the ignition is turned ON. The control module then saves this value as the barometer value. |
| TPS SIGNAL | = | Throttle position sensor |
| SIM. IDLE POS.SW | = | Simulated throttle switch. The values determined are calculated by the control module on the basis of the throttle position sensor voltage. |
| PARK/NEUTRAL SW. | = | Selector lever position (only automatic transmission) |
| EGR SOLENOID | = | Solenoid valve for addressing the exhaust gas recirculation valves |
| EVAP CONTROL V. | = | Evaporation control valve. This valve is located between the carbon canister and the inlet manifold. It regulated the flow of fuel vapour. |
| VEHICLE SPEED | = | Travelling speed of the vehicle |
| DESIRED IDLE | = | Nominal engine speed (selected in TECH 1 mode with "F7") |
| ENGINE SPEED | = | Actual engine speed |
| IDLE AIR CONTROL | = | Idle air control compensation stepper motor, idling speed regulator |
| SPARK ADVANCE | = | Ignition timing |
| O2 SENSOR LOOP | = | Open / closed reguation loop |
| O2 SENSOR | = | Oxygen sensor voltage |
| O2 INTEGRATOR | = | Oxygen sensor integrator (part of the control module for detection of control deviation between nominal mixture and actual mixture) |
| O2 BLM ENABLE | = | O2 block learning mode switched on : ACTIVE / INACTIVE |
| O2 BLM CELL NO. | = | O2 block learning mode cell number (in these engines there are more than two O2 block learning cells. If the cell number for idling speed is not reached, the throttle position sensor should be checked) |
| Note! The text "No." does not appear in the German TECH 1 display. | ||
| O2 BLM CELL CONT | = | O2 block learning mode cell content (the nominal content should be compared with the data list. Pay special attention to the correct cell number!) |
| Note! The text "No." does not appear in the German TECH 1 display. | ||
| AIR/FUEL STATUS | = | Air / fuel ratio: LEAN / RICH |
| AIR/FUEL RATIO | = | Air / fuel ratio: numeric value less than 14.7 = rich |
greater than 14.7 = lean
| POWER ENRICHMENT | = | Power enrichment: ACTIVE / INACTIVE |
|---|---|---|
| A/C INFORMAT. SW | = | Air conditioning switch in passenger compartment |
| A/C RELAY | = | Air conditioning relay for operating the AC clutch |
| POWER STEERING | = | Control module input to record the steering assistance signal (power steering) |
