C1900 Chevrolet Spark OBD Code

OBD/2 C1900 error code description and symptoms.

Low Speed Fuel Pump Primary Circuit Malfunction The PCM monitors the low speed fuel pump (LFP) primary circuit output from the PCM.
The test fails if: When the LFP circuit is commanded on (grounded), excessive current draw is detected on the LFP circuit; or when the LFP circuit is commanded off, voltage is not detected on the LFP circuit (the PCM expects to detect VPWR voltage coming through the low speed fuel pump relay coil to the LFP circuit). Open or shorted low fuel pump (LFP) circuit Open VPWR to low speed fuel pump relay Damaged low speed fuel pump relay Damaged PCM An open circuit or short to ground can only be detected with the low speed fuel pump.

Circuit High Input codes like C1900 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

C1900 Chevrolet Spark Error Code Repair Process :

If your c1900 steering vaps ii circuit loop short to ground check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system C1900 and engine control unit are in charge of monitoring a bunch of different c1900 steering vaps ii circuit loop short to ground, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Chevrolet Spark C1900 OBD2 Code

A common cause of code C1900 is the failure of C1900 Steering VAPS II Circuit Loop Short To Ground, but there are several other possible causes as well, such as ;

EVAP canister or fuel tank leaks
Damaged VCT phaser
Ignition misfiring
Intake Valve Timing Control Solenoid Valve harness is open or shorted

C1900 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
