Toyota Engine Fault Codes

P00B0

Failure or errors in the operation of the turbine control module or a malfunction in the operation of the second-row turbine itself. A possible cause may be air leaks, so all pipes and connections of the system must be checked.

P0011

If on Toyota Avensis in the back of 270 or another model this code caught fire, this indicates an incorrect position of the engine camshaft.

Possible causes of the malfunction:

P0012

If an error occurs, P0012 indicates a malfunction of the valve timing control. The problem may result from a low level of engine fluid in the powertrain. The appearance of the code is sometimes due to improper installation of the camshaft, timing control drive or timing belt.

More on what to check:

  1. Strainers for the solenoid valve for the variable valve timing. These items may be clogged or torn, sometimes they are not installed correctly.
  2. Leakage of engine fluid at the seating surfaces of the valve seals of the valve timing device.
  3. Interruption of the supply of motor fluid to the solenoid valve of the drive mechanism.
  4. Timing drive belt integrity for wear.

P0015

Invalid valve timing, opening angle too late

P0016

Code P0016 appears as a result of a violation of the relationship between the camshaft and crankshaft. The cause of the problem may be related to the wear of the gears on the pulleys, as well as the malfunction of the sensors, but the second option is less likely. Sometimes the error appears as a result of wear and tension of the timing chain.

P0018

Code 0018 reports a phase mismatch in the gas distribution system

P0104

P0104 appears when there is a malfunction of the mass air flow sensor

P0170

Violation of the fuel balance in the engine. The user needs to find and eliminate the cause of depletion or enrichment of the combustible mixture.

P0401

Low efficiency in the operation of the exhaust gas recirculation system. If all the sensors are intact, then you need to check the operation of the pipes and hoses – the cause of the problem may be air leakage. If there is no leakage, the clamps should be checked, since one of them could weaken. If these steps did not help to eliminate the cause, then it may be the microprocessor module.

P0046

Combination P0046 reports a malfunction in the turbocharger pressure control solenoid valve. The cause of the error may consist in the failure of the drive pressure device.

P0048

Malfunction in the solenoid valve of the turbocharger pressure control system. The drive pressure device may be generating a signal that is too high.
