They may also comment some instrument/radio displays are erratic. Upon investigation, the technician may find DTC C0900 set. If the displays were erratic, then DTC B1325 will also be set. Cause This condition may occur when the system voltage exceeds 16 volts for one second for code C0900 and the system shuts down to protect it from over-voltage operation. If the voltage exceeds 18 volts for five seconds for code B1325, then other electronic systems protect themselves and shut down. It has been found that this voltage increase is caused by an interaction between the alternator and the ignition coil/module assembly.… Read More

1996 Chevrolet Chevy K Pickup Ignition Coil Control Circuit High Voltage

Filed Under (Chevrolet (Chevy)) by admin on 21-12-2013

Download 1996 Chevrolet Chevy K Pickup – 4WD | Chevy Pickup, GMC Pickup, Suburban, Tahoe, Yukon (VIN C/K) Service Manual DTC P1351 Ignition Coil Control Circuit High Voltage. Circuit Description The enhanced ignition system uses the crank sensor in order to provide the timing input to the VCM. The VCM uses this reference pulse in order to determine the individual ignition spark timing for each cylinder. Once the VCM calculates the ignition timing, the ignition coil module on the IC circuit receives the timing signal. Each timing pulse received by the ignition coil module on the IC circuit triggers the coil module in order to operate the ignition coil. The secondary ignition voltage is induced, and then the secondary ignition voltage is sent to the distributor for distribution to each spark plug. This DTC is a type A DTC. The IC signal voltage ranges from about 0.5 volt to 4.5 volts.… Read More

DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected

Filed Under (Other Manuals) by admin on 17-01-2014

Download DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected Refer to Engine Controls Routing Diagram, EVAP Control System Overview . System Description This DTC tests the evaporative emission (EVAP) system for a small leak. The control module monitors the fuel tank pressure (FTP) sensor signal to determine the vacuum decay rate. At an appropriate time, the control module turns the EVAP canister purge valve ON and the EVAP vent valve ON. This allows the engine to draw a vacuum on the EVAP system. At a calibrated time, or vacuum level, the control module turns the EVAP canister purge valve OFF, sealing the system, and monitors the FTP sensor input in order to determine the EVAP system vacuum decay. If the control module detects a leak larger than a calibrated amount, this DTC sets. The following table illustrates the relationship between the ON and OFF states, and the Open or Closed states of the EVAP canister purge and vent valves.… Read More
