If necessary, recalibrate the ECM. 7 volts with the engine off, and 13. Intuitive and easy-to-use PC software design to work exclusively with the EC Titanium Integrated Drive and Motor product line. If the ECM detects PNP signals with low voltage, it sets a diagnostic trouble code, DTC P0851 – Park Neutral Position Low voltage on 5v reference wire. Only one PCM would be used for the reference voltage since both use 5vdc as a reference. If you have 12-10v on ECM wire then its not a low voltage The ECM decodes the serial data signal and is used as voltages for throttle position sensor 1 and 2. blyne3. Reconnect leads and apply low--voltage power to "What is normal alternator output voltage? The voltage should read a minimum of 13 volts. If the battery voltage fails to meet normal operating parameters, a code is set. Tax. sensor supply voltage (+) battery supply wires. What is specific to each injector is a 12V- (negative pulse) via the engine ECM. Check that the knock sensor is receiving the correct voltage. 7 volts. 7-14. 7 Voltage after shutting down ~12. When battery voltage is removed from this input, the ECM will power down. Can this voltage be measured at the 12v outlet (aka cigar lighter) . When this component fails, it sends incorrect voltage signals to the engine control module (ECM). So you will never have 12v there. 1 Review P0120: Throttle Position Sensor/Switch A Circuit Malfunction – this code shows the voltage rises or drops more than normal or otherwise stutters when compared to the “B” . 3.
