What causes the p0084 OBD-II trouble code?
P0084 code is set when the ECU tries to control the exhaust valve timing on bank 2 and detects a fault. This fault triggers a Check Engine Light to be seen on the dashboard and a failsafe mode to be activated. Variable valve timing is also disabled due to the failsafe. What causes the P0084 code? What are the symptoms of the P0084 code?
What causes an ECM to fail a p0123 code?
Most failures for code P0123 involve a defective TPS sensor, or a connector shorted internally. All TPS codes will cause the ECM to go into the same failure mode; drive symptoms will be roughly the same. Need help with a P0123 code?
What are the symptoms of the p0123 OBD-II trouble code?
The TPS sensor circuit A range output to the ECM went above the specified voltage of 4.54 volts for more than 2 seconds, indicating a short in the sensor or wiring. What are the symptoms of the P0123 code?
What is the diagnostic code for throttle pedal position sensor?

A similar code is P0335, Crankshaft Position Sensor “A” Circuit Malfunction. Like P0340, P0335 also warns about a problem in a sensor’s electric circuit. The difference is that P0335 covers the crankshaft that converts engine power into forward motion, while P0340 involves the camshaft that controls the intake and exhaust valves.
Why does my engine code keep coming back?
So you decide if you want to take the risk. After all, the most common problem with this trouble code is actually a faulty camshaft sensor.
