C3834 Trouble Code

View C3834 obd/2 error code description and symptoms. C3834 engine photo

Vehicle Speed Sensor (VSS) Intermittent Indicates the powertrain control module (PCM) detected an error in the vehicle speed information. Vehicle speed data is received from either the vehicle speed sensor (VSS), transfer case speed sensor (TCSS), anti-lock brake system (ABS) control module, generic electronic module (GEM), or central timer module (CTM). This DTC is set the same way as C3834. However, it is intended to flash the transmission control indicator lamp (TCIL) for first time VSS circuit error/malfunctions. Refer to possible causes for C3834

As the engine heats up and combustion becomes easier and more complete, the PCM will command the idling control valve to increase the amount of air entering the engine to suit the changing conditions. However, when the load on the engine changes, say, when some electrical consumers or other systems are either turned on or off, the PCM adapts the signal voltage to the idle control valve to ensure that the idling speed remains stable, and at the RPM specified by the manufacturer.

C3834 Error Code Repair Process :

If your accelerometer front circuit failure 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 C3834 and engine control unit are in charge of monitoring a bunch of different accelerometer front circuit failure, and if they get a reading that's a little out of whack, up pops the check engine light.

C3834 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.

Common Causes of C3834

A common cause of code C3834 is the failure of Accelerometer Front Circuit Failure, but there are several other possible causes as well, such as ;

EVAP system hose leaking
Faulty front heated oxygen sensor
Fuel tank leaking
Air fuel ratio (A/F) Sensor 1 Bank 1 harness is open or shorted
