View U268A obd/2 error code description and symptoms. U268A 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 U268A. However, it is intended to flash the transmission control indicator lamp (TCIL) for first time VSS circuit error/malfunctions. Refer to possible causes for U268A

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.

U268A Error Code Repair Process :

If your scp (j1850) invalid or missing data for chassis status request 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 U268A and engine control unit are in charge of monitoring a bunch of different scp (j1850) invalid or missing data for chassis status request, and if they get a reading that's a little out of whack, up pops the check engine light.

U268A is a kind of Network Trouble Code

U-code indicates that engine communication errors and shows lost communication with engine parts.U-Codes are fairly straight forward, given all of the articles and technical publications that have been written regarding these problematic codes. In most cases, it just comes down to identifying the module that isn't communicating with the other modules on the CAN bus line for whatever reason.

Common Causes of U268A

A common cause of code U268A is the failure of SCP (J1850) Invalid or Missing Data for Chassis Status Request, but there are several other possible causes as well, such as ;

EVAP system hose leaking
Faulty ignition coil (s)
Failures of clutch motion/travel sensors.
1Camshaft Position Sensor circuit poor electrical connection
