These three (3) new gauges give meaningful information that points directly to a possible cause of the P0020 code. PID # 16CF "acronym CAMDCR" - Commanded Duty Cycle for VCT Solenoid, in (0-100) % PID # 16CE "acronym CAMERRR" - VCT Error in Crankshaft Degrees, in (-/+) DEGREES PID # 16CD - "acronym RCAM" - VCT Solenoid Commanded in Crank Shaft Degrees, in (-/+) DEGREES So far, I have identified - developed ("?working") formulas and guages for: I have been working to decipher these PID's - Specifically to create and add custom PID's to the Torque App for new gauges relating to the Variable Valve Timing system (VCT). Of course, their raw data (at least initially) is pretty much hieroglyphics. With my Torque App's "Torque Scan" function, I developed a list of PID's (214 of them) that the ECU actually responds to. I wanted more diagnostic information about the system for making more informed decisions. I am aware the variable valve timing system (Cam Phasers, VCT Solenoids, CPS Cam Position Sensors) is often suspect on these engines - and can produce a wide range of symptoms - often mistaken for other problems. My '04 F150 5.4L 3v engine has thrown a P0022: code a couple of times lately. ANYONE know the PID (Perameter ID) that gives actual Engine Oil Pressure reading on an OBDII diagnostics system of any vehicle make? I actually have a Ford truck, but since the OBD system is supposed to be a standard (although freequently not so), I can check ANY PID # via my Torque Pro app.
