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 P04BD. However, it is intended to flash the transmission control indicator lamp (TCIL) for first time VSS circuit error/malfunctions. Refer to possible causes for P04BD

Circuit High Input codes like P04BD 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.

P04BD Error Code Repair Process :

If your evaporative emission (evap) system flow during non-purge chevrolet only 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 P04BD and engine control unit are in charge of monitoring a bunch of different evaporative emission (evap) system flow during non-purge chevrolet only, and if they get a reading that's a little out of whack, up pops the check engine light.

P04BD is a kind of Powertrain Trouble Code

Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.

Common Causes of P04BD

A common cause of code P04BD is the failure of Evaporative Emission (EVAP) System Flow During Non-Purge Chevrolet Only, but there are several other possible causes as well, such as ;

EVAP system hose leaking
Faulty oil control valve (OCV)
Faulty Camshaft Position Sensor
Lack of fuel
