You're most welcome, happy to help.

Put some SeaFoam in the tank and call it good. I would recommend cleaning your Throttle Body, and if you drive like grandma, I'd say a DIY decarboning is probably in order. If you get on it once in awhile then you can skip that.

Those are the IVT solenoids, they're hydraulic valves which drive the camshaft phasers to advance or retard intake timing. They did the work for reasonable labor and I'm glad it's running well, but they sure did sell you a bunch of stuff you didn't need.

VStar650CL

No, you're misinterpreting that. The 23731-AL61D is the crank sensor, but since it's used as either crank or cam on various models, the catalog description is "cam sensor". The total number is correct, the phase and two IVT sensors are all identical so quantity for those is 3.

VStar650CL

Oh, yah, I'm not surprised at the parts prices either. Dealerships all charge "list plus" over the counter, and it's always way more than you'd pay online. It's a racket. I give all my best customers a break by pointing them at NissanPartsDeal.com, that's factory-warranty stuff and it's sold at list ...

VStar650CL

Yep, that's a correct manifest. The crank sensor is the only one with a different part number, the phase sensor and the two IVT sensors all use the identical part. The labor doesn't seem out of line considering they changed the solenoids too, those face inboard on the VK and one of them is a ...

Yep. The IVT sensors have their own set of codes and I've never seen an ECM confuse them like it can with crank and phase. Replace just those two, the IVT sensors ain't broke and you shouldn't fix them.

VStar650CL

The principle tell would be replacing the phase sensor with an OEM one and the P0340 doesn't clear, but then you still need to check the wiring before condemning the ECM. I don't go around advertising it in here without a reason, but I'm a Nissan master tech in a midwest dealership, electrical ...

Change green plus the crankshaft sensor. Leave the blues alone. Green is the one throwing the P0340.

VStar650CL

It wouldn't be total of 3, it would be total of 4. One crank sensor, one cam (phase) sensor, two cam (IVT) sensors. Except the only one throwing a code is phase. Change that and the crank, leave both IVT's alone.

VStar650CL

You're not getting this about "both" cam sensors. The VK56 actually has three cam sensors, plus the crank sensor. The one which is throwing the code is the "phase" sensor, which is actually clocking the left cam's mechanical position before any phasing. Then there are "IVT control" sensors on each ...

VStar650CL

Aargh. Every one of those codes is potentially derivative except the cam sensor. The P1819 might be something to worry about, but only if it doesn't erase after the P0340 is fixed. I hate to say it, but you're getting your d!ck pulled.

VStar650CL

Actually, I missed that you had a VK and not a VQ. P0340 on a VK is specific to the "phase" sensor which is located below the lefthand "IVT control" sensor on the front left of the engine. The crank sensor can falsely cause the ECM to blame the phase sensor in some cases, so I'd replace those two ...

VStar650CL

For the most part I do recommend that my customers replace both if they can afford it. The biggest thing is, aftermarket sensors are a bad idea. There are lots of places on any Nissan where aftermarket parts do just fine, but Hall sensors aren't among them. Use OEM.

VStar650CL

All of those codes are derivative crap except for the P0340. That code caused the ECM to temporarily stop transmitting the engine speed signal. That in turn caused the C1130, which in turn made the ABS stop transmitting the vehicle speed signal. Then everything else said, "Duh." Once you cycled the ...
