ENGINE 1.3 QUADRAJET (75PS) 9 4 Fig. 183 OPERATION The accelerator pedal position is converted into an electrical voltage signal and sent to the injection control unit by the potentiometer connected to the pedal. The accelerator pedal position signal is processed together with the information relating to the engine rpm to obtain the injection times and the pressure PIN OUT Pin Description Signal type 1 Track 2 supply 5 V input 2 Track 1 supply 5 V input 3 Track 1 earth Earth 4 Track 1 signal Analogue output 5 Track 2 earth Earth 6 Track 2 signal Analogue output BOSCH SENSOR TECHNICAL SPECIFICATIONS Supply voltage: 5 V +/- 0.3 V Resistance at potentiometer cursor terminals: 1 Kohm +/- 0.4 kOhm Track 1 resistance: 1.2 Kohm +/- 0.4 kOhm Track 2 resistance: 1.7 Kohm +/-0.8 kOhm HELLA SENSOR TECHNICAL SPECIFICATIONS Supply voltage: 5 V +/- 0.3 V Resistance at potentiometer cursor terminals: 1 kOhm +/- 0.4 kOhm Track 1 resistance: 0.9 kOhm +/- 35%....1.4 kOhm +/- 35% Track 2 resistance: 1.2 kOhm +/- 35%....2.0 kOhm +/- 35%. H. AIR FLOWMETERWITH BUILT INAIR SENSOR SPECIFICATIONS The debimeter is located on the air int ake sleeve and is hot film type.
