Check P0043 Fault Code
When you check engine light came on code P0043 the reason should be Engine Light ON (or Service Engine Soon Warning Light). However your vehicle's manufacturer may have a different definition for the P0043 OBD-II Diagnostic Powertrain (P) Trouble Code. So you should chech it on our car models.

P0043 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set. |
P0043 Possible Fix :
Probably the biggest result of injector failure is due to the injectors having excessive return flow or back leakage. This is due to worn parts which allow excessive fuel to go through the diesel injector and to return back to the tank or fuel system. This causes a drop in rail pressure which results in hard starting or not starting at all.

P0043 Solution:
Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

How to Clear P0043 Trouble Code
An OBD 2 scanner is the best and safest way to erase a DTC from your car's system. This scanner communicates with the car's computer and instructs the computer to erase the code. It does not change or tweak the settings from inside the car or its systems.
