2007 LS 460 - Check engine light came on one morning when pulling the car out from the garage. I plugged in my OBD data collector and received two fault codes: P1363 and P1365

Has anyone experienced these OBD codes? The printouts I received from the helpful Lexus parts guy shows a cam position sensor fault code or VVT fault code. Has anyone changed the sensors or wiring associated with them?

 

P1365 is "C" Camshaft Position Actuator Circuit Open, Low, High Bank2

P1363 is "B" Camshaft Position Actuator Circuit Open, Low, High Bank2

So it looks like you have a bad PCM, short, or bad connection. I believe bank 2 is the passenger side. If you've recently had any work done, perhaps they didn't reconnect a harness properly

 

Where are these modules located on the passenger side? The fuse box is near the headlights and there's a larger box closer to the battery which looks like it holds the ECM. Thanks in advance.

Also, I'm feeling some hesitation in acceleration in mid RPM range. I have read that some folks get the ECM flashed. Have you heard of this?

 

You have to keep in mind that a fault code dose not mean a component fault. I wish it was that easy.
The fault code gives you a hint to a larger picture of where the problem is occurring upstream.
I would first check the connections. It is possible as RF mentioned that a loose connection possibly at the ECU or anywhere in between the wires may have been cut could be the fault. I would invest in a multi meter to track it down. Don't over think this with ECU flashes and such.

 

 

designzio, did you ever figure out what it was? I have the same problem right now with my LS460. Can't find the fault.

 

Yes I did. It turned out to be the electric cam motor. It was about $1500 at the dealer. I have since sold the car and bought a CPO '13 GS350.

 

Wow $1500? That's insane.

 

Yes it is.....considering you can get them on Ebay for 249 dollars. But that's dealer pricing for ya.

 

That one for 249 dollars on eBay is a used unit, new ones are $500, certainly no bargain.

The only good news is that you CAN drive the car with this problem, until you figure out what it is and fix it. I don't think the average person could easily diagnose this, which unfortunately would mean most people would have to take it somewhere...and be charged a diagnostic fee...probably a $100 bucks at most places,that would either be waived/reduced if you had it fixed there, but I imagine the total bill at most places would be around $700 (parts and labor).

If you ever run into a problem like this let me know, I have access to diagnostic programs that may save you from taking it somewhere.

That cam actuator is one of the first - if not the very first - electric cam phasing units on a vehicle...most are hydraulic...the opposite cam on our cars is hydraulic (one electric and one electric). I always figured the electric actuator would fail...hopefully mine won't.

 

This wasn't the only problem fixed for the $1500. Two cam position sensors were also replaced as well as diagnosis. The car was barely road worthy with the cam motor out. Lots of acceleration hesitation and stalling between 1st, 2nd and 3rd gears. This is the first engine with this configuration: VVT-ie. Along with the air suspension problems, that car was a nightmare. However, the ML sound system was incredible.

 

Sounds like the dealer took you for a little ride by replacing the cam sensors as well, because there's no way in hell all three things needed to be replaced. What probably happened is the young tech followed the diagnostic tree, but screwed up in the testing procedures for the components, and instead just replaced everything...finally fixing the thing. Cam sensors usually don't go bad...certainly not two at once.

It sounds like you had horrible luck with the car, I would have sold it too. If I start experiencing an abundance of problems with my 07 ls460, I'll trade it in pronto for a 2013-2014 ES350. I know it's a step down, but those things are nice looking and bullet proof...takes regular gas too. But so far my car has been pretty good, I'll be replacing the control arms and a bearing soon, but other than that it's been good. I can do all those repairs myself for around $600.

 

I have a 2010 lexus ls460 mine code recently came up after having the valley plate resealed its popping a p1365 vvt sensor/cam position sensor code an it's hard to start the car I have an appointment at the dealership was any of you guys car hard to start an using excessive fuel.

 

Hi I have a 2010 lexus ls460 also an it's doing the exact same thing after having the valley plate resealed what was the fix for this.

 

I have p 1365 it was taking to the dealership they fixed the code issue said wires were pulled upon having the valley plate leak fixed they put new connections on the end of the wires code went away but my car is still hard to start and using excessive fuel
