Common cause for Daihatsu Kopen P3169 is the valve is controlled by the PCM (or a similar controller) using inputs from sensors and other controllers in the controller area network (CAN). The CAN represents a communication bus that allows multiple microcontrollers.
Common Symptoms For Daihatsu Kopen P3169
Look for loose or corroded electrical connectors that may increase circuit resistance and cause these types of codes to be stored. Obtain a CAN bus system wiring diagram and/or pin out value chart, and then use the digital volt ohmmeter to test continuity between individual controller connectors
As the input shaft is turned (by the engine) the electro magnetic input/turbine speed sensor uses the spaces between the splines to provide voltage signal interruptions in the circuit
If either the reference voltage or ground circuits are open, use the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in both circuits
Several tools will be instrumental in successfully diagnosing this code
Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
TFP Valve Position Switch-Drive Without Drive Ratio
Daihatsu Kopen P3169 Troubleshooting
White smoke means that the fuel that is being injected into the combustion chamber is not being burned properly. The common causes that produce white smoke range from something as simple as low engine compression or water in the fuel to the fuel pump timing being thrown off because something is starving the fuel from getting to the pump in the manner necessary for the pump to time and work correctly. Parts or components should not be replaced with reference to only a Daihatsu Kopen P3169 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
How to turn off Daihatsu Kopen P3169 check engine light ?
There are two ways to turn off the check engine light:
A repair technician can do so once repairs have been made.
The OBD II can automatically turn it off when it fails to detect the problem after several diagnostic cycles.
