Possible symptoms- Engine Light ON (or Service Engine Soon Warning Light)- Possible engine lack/loss of power- Possible engine rough idle P1140 Nissan Description This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.The Engine Control Module (ECM) receives signals such as crankshaft position, camshaft position, engine speed, and engine coolant temperature. Then, the ECM sends ON/OFF pulse duty signals to the intake valve timing control solenoid valve depending on driving status. This makes it possible to control the shut/open timing of the intake valve to increase engine torque in low/mid speed range and output in high-speed range.The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the i

Found some info on reading out the pins (can't remember where) which was turned out to be worthless (at least on my $20 multimeter). None of the pinouts read anything ON EITHER SENSOR. Since both sensor's had the same ohmmeter readings, I wanted to be sure, so I swapped them. Sure enough the code swapped to P1145. Ordered the part for ~$50 from Pinnacle Nissan, installed on the DRIVERS side (remember - I swapped them as part of the troubleshooting). Voila! - No more SES and the car is happy.Fast Forward. 2 days ago the SES came on. Popped my trusty CarChipE/X onto the port and what do you know - P1140. So apparently the passenger side (old driver's side) sensor has crapped out now also. I will order the new part tomorrow but I have a couple of "hmmmm . . .s"Did I somehow break the sensor by: (a) swapping it around (b) fiddling around with an ohmmeter (I tried every pin-to-pin combo to see what I would get after the all readings except one read "open" on both the good and bad sensor.Is it not really the sensor but actually a solenoid problem? (I AM getting the SES light as soon as I turn the motor over which the
