An air leak forward of the DPF will change the sensor readings resulting in the code Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks. A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture. How do you troubleshoot P0916 ? The engine system, in conjuction with the engine control module (ECM)/powertrain control module (PCM), activates the P0916 code solenoid valve to control oil pressure to the engine mechanism that is installed in the valve system to switch valve timing between Low and High.If the engine solenoid valve has an open or short circuit, a DTC is stored.
