Check engine light p1078
#16
Folks,
Resurrecting this thread... At 170,000 miles on my '05 6MT, I have the P1078 code and the SES. I also noticed that the variable valve timing does not engage at 3800 rpms (I thought it may have kicked in over 5000... I stopped rev'ving that high since then... going to wait until I've replaced the sensors and cleared the SES indication).
I'm planning on getting the replacement sensor, but I wanted to know: How do I tell if the sensor that is out is on the driver or passenger side (Bank 1 or Bank 2)?
Thanks in advance!

So I have had the same problems, started with hard to start and Vcd/slip light on (Forget the code) , changed both intake cam sensors and it went away , then a few days later p1078 code shows up with high idle so I replaced both exaust cam sensors, light went away...a few days later it came back so I replaced the crankshaft sensor and still the same problem...what can I do now? Car has no power!

I got the same code P1078, which I think is the Exhaust Valve Timing Control Position Sensor Bank 1. From what I understand, it is also called the camshaft position sensor. I asked a parts guy, and he told me that the code is for part 23796-EA200, which is the solenoid. I thought the code was likely for the sensor and not the solenoid. Anyway, I think the sensor that needs to be replaced is 23731-AL606, but I'm not sure. It seems like the sensor is the straight one for bank 1 (passenger side). If it's just the sensor, it seems like an easy fix as long as I know the correct sensor. Does anyone know that exact part number? I would prefer to replace it with the OEM sensor.

Hey brother so the P1078 is the sensor for the exhaust cam on bank 1 which is the passenger side. The part number you will need is a 23731-AL61D. It is the angled sensor on the passenger side. The straight one on passenger side is for the intake cam and that would be a P0340 code for that particular sensor.

Thanks for the help! That clears that up, but confuses me also. Is there a video or diagram of where the exhaust camshaft sensor bank 1 is located? At the risk of sounding stupid, I thought there were only two to replace...bank 1 (straight and on passenger side) and bank 2 (angled and on driver's side).

Me personally because I have worked on these cars for so long, take the 10mm bolt out of the purge solenoid bracket(back of intake on passenger side) that is the solenoid that has the 2 black hoses coming off of it. Take it completely off with the hoses attached. I just use a 10mm wrench to loosen cam sensor bolts and then pop them out that way. Now I will tell you if you do go and buy the OEM sensors which I am hoping you do, they are a new design and look different than the sensor you take out. The new sensors have a metal end. This is normal so don't be alarmed. They are correct. Hope this helps brother...

I'm able to reach 3 of them fairly easily from the passenger side. The exhaust one on driver's side is a bit of a stretch, so went ahead and removed the intake for better access.
I made the mistake of originally getting generic sensors, and had to replace them in a year. So I've had practice, lol.
One other random thing I noticed, the angled and strait sensors are on the same relative position at the back of each head. Strait on left, angled on right. You can see it in that picture posted above. Useful in case you remove all 4 and then go "crap, now what."

Thanks for the help...I got it fixed with that OEM part. Everything was working fine until the other day my car just shut off while driving, and today when I was driving, the slip light, VDC light, and the SES light turned on. I ran the code and got P0340. It's also having a hard time starting up, but I'm not sure if that's the sensor issue or a battery issue, too.
