Help with Code P1092: VVEL Control Shaft Position Sensors

Stino · 04-11-2016, 10:59 AM

My car went into Limp Mode a few weeks back. I scanned for the trouble codes using my Innova scan tool and Cipher and both scanners came up with P1092 on Banks 1 and 2. I’m also getting codes U1024 & C2849. I have UpRev and other mods installed, please see the list below.

I did a little research and found in the 2010 370Z spec manual that code P1092 is triggered by the “VVEL Control Shaft Position Sensor”. Before doing anything, I use Osiris to flash the "back to stock" ROM for my ECU.

In the manual, it states that the voltage for both VVEL Control Shaft Position Sensors need to be 500 + 48 mV. I checked the VVEL Control Shaft Position Sensor voltage with Cipher and was getting a voltage reading of 648 for both banks. Following the instructions in the manual, I loosened the mounting bolts and adjusted the VVEL Control Shaft Position Sensors to a voltage of 499-504 using Cipher as the tool to visually adjust the voltage. I then followed the remainder of the instructions by turning the ignition off for 10 seconds then letting the car warm up, etc. I checked the codes using Cipher again and found that there were no codes found.

I took the car out for a spin around the block and within two minutes the car went into limp mode again. When I got home, I scanned for codes using the Innova scan tool and Cipher and found that the P1092 codes came back and the sensor voltages now reads 600 for Bank1 and 648 for Bank2. Hmm…why and how did voltages change after making the adjustment?

I’m at a loss, can anyone please offer some advice. Thanks!

I replaced the VVEL relay in the engine bay (next to battery) there are 2 relays side by side. When the code came back I realized that both VVEL sensors going bad at the same time was rare..... so I replaced the VVEL module (found it online for $120, NEW is $800 from Nissan) swapped it in and never had an issue and never replaced any vvel sensor.

where did you find the vvel online? ebay? will need to replace mine down the road because one of them is leaking and i was told you should replace both

My Z is fixed and running better than ever. I replaced the VEL control Module, adjusted the VEL Actuator Sensors myself with UpRev software and didn't have to part with $3200 like the Nissan dealer said I needed to.

When I took my car to Nissan and supposedly spoke to their top mechanic, he had no clue what I was talking about until I showed him in the 370Z service manual. There is absolutely no excuse for that if you are the top shop mechanic.

Do yourself a favor and read the service manual; you'll know just as much as the Nissan Dealer Mechanics.

I know it's been a couple years but thank you for this thread. I had no idea I could adjust the sensors with uprev. Set my zoom on max and fixed my issue as well after replacing the vvel control module. Cheers!

i have a quick question for you, when you checked your voltages where they staying the same?

I have this really weird issue where the voltage on my VVEL sensor stays the same no matter how i turn the camshaft or the sensor. if its on its on at 680v if its off its off. the passenger side (bank 1) is perfect and is within spec

was wondering if you knew how to fix it and if you had the same issues

Thanks
