What does the p0190 code on my 2008 VW tiguan mean. It does have a rev problem


no it will not ,it may blow the big ends but it will not throw any code ,this code you quoted does not exist in my ford code list but on the universal OBDII


P0190 Fuel Rail Pressure Sensor Circuit Malfunction

could be a loose sensor?? or a dirty connection on the plug?

CODE 89 IS FUEL PRESSURE REGULATOR 1 PERFORMANCE.CODE 642 SENSOR REFERANCE VOLTAGE CIRCUIT "A" LOW.AND CODE 2004 IS ITAKE MANIFOLD RUNNER CONTROL STUCK OPEN.CK FOR BAD OR MISSING VACUUM LINES.IS IT STILL UNDER WARRANTY

Code p 0190 refers to fuel rail pressure (FRP) sensor---circuit malfunction===causes --wiring--fuel rail pressure sensor ---ECM
replace the sensor

You will need to google this, we do not have this type of data base to draw on.
