DF214 Proton 300 OBD Code

OBD/2 DF214 error code description and symptoms.

The input turbine speed sensor detects rotation of the input shaft of the input shaft speed sensor transmission. The computer uses that information, along with the output shaft speed sensor to determine if the transmission is operating according to plan. If the computer detects a difference between the input shaft speed , and the expected output shaft speed, it will adjust transmission pump pressure to prevent clutch disc slip. If adding pressure doesn't solve the problem, it will set a trouble code.

Circuit High Input codes like DF214 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.

DF214 Proton 300 Error Code Repair Process :

For scp (j1850) invalid or missing data for primary id / vehicle speed check engine light is perhaps the most troubling of lights because it could mean so many different things, from you didn't screw the gas cap on tightly enough to look out for pistons flying through the hood and into the stratosphere. The easiest way to find out what this light is telling you is to hook your vehicle up to a scan tool. DF214 error code diagnostic tool looks a little like an oversized calculator and plugs into a communication port inside the car. After you instruct it to perform the scan, it speaks scp (j1850) invalid or missing data for primary id / vehicle speed with your car's computers to find out exactly what's prompting the light to turn on.

Common Causes of Proton 300 DF214 OBD2 Code

A common cause of code DF214 is the failure of SCP (J1850) Invalid or Missing Data for Primary Id / Vehicle Speed, but there are several other possible causes as well, such as ;

Faulty Air Flow Meter
Faulty starter motor
Fuel injectors harness is open or shorted
Faulty Camshaft Position Sensor
