B1147 Kia Rio Iii OBD Code

OBD/2 B1147 error code description and symptoms.

Output Shaft Speed sensor circuit intermittent failure The output shaft speed sensor signal to the PCM is irregular or interrupted.
Harness connector not properly seated Harness intermittently shorted, or open Harness connector damaged OSS sensor damaged, or not installed properly Verify harness and connector integrity Verify OSS sensor proper installation.

Circuit High Input codes like B1147 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.

B1147 Kia Rio Iii Error Code Repair Process :

If your vehicle failed a B1147 test and the B1147 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses servo motor potentiometer airintake right circuit short to battery a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look servo motor potentiometer airintake right circuit short to battery: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Kia Rio Iii B1147 OBD2 Code

A common cause of code B1147 is the failure of Servo Motor Potentiometer Airintake Right Circuit Short To Battery, but there are several other possible causes as well, such as ;

Camshaft Position Sensor harness is open or shorted
Exhaust gas leaks
Faulty Crankshaft Position Sensor (POS)
Intake Valve Timing Control Solenoid Valve harness is open or shorted
