obekediamondfuto:
me, I maintain that if u have used 20w50 more than 3 service change intervals then stick with it. it'll burn oil and leak thru the seals if u switch to factory which translates to shorter service intervals.


autoelect I hail u, I would love to visit and learn more from u.. most of my expertise comes from just the Toyota brand, a Lil hands-on experience with other brands wouldn't hurt.

I would like to address the bolded section in a subsequent post.

Join my e-learning program, you will get access to the same stuff they use to teach automobile technicians in the US of A. It will cost you just N100,000.00 and you will have access for 6 months. more details available here: https://www.nairaland.com/4560475/american-automotive-technician-training-live

OK boss, I'll look it up.

I'm still quite new in this industry, heck I started out as ikenna and now I'm pushing forward in every way possible cos this is a trade I'd love to indulge in without thinking of it as a Job.... like my current JOB.

to be Candid, Gazuzz inspired me and is more of s mentor to me in this biz. but all the same, no knowledge is wasted. if I find reasons to doubt any aspect of my current knowledge, I will doubt and proof it the the very best of my ability.


thanks once again for the offer.

To the OP, I feel your pain here.

Some questions for you though.
1. How many miles on her now?
2. I can only see pending codes on the results. Is the code that is on display what they did fix?

Here are my humble submissions:
1. If the code on display, was a current code, and not a pending one, replacing the camshaft sensors, as you claimed, won't solve that problem.

In some cases, it does.

Basically, what is happening on that car are as follows:
a) you may have being using wrong viscosity engine oils for your car. For instance, of you use, say, mineral oils, with its limited additives in them, with time, theses additives that are part of mechanism needed for lubrication of internal engine parts, gets oxidized,and degraded, causing sludge buildup that would if not checked, hamper the operations of the car's VVTi system.

b) is either the vvti itself is faulty, and not the camshaft sensors that were replaced.
Inspect the wiring harness on the vvti circuitry, and even the camshaft sensors wires also.
If the wires are chamfered, the signals emanating from the vvti/camshafts would be erratic, and the ECU won't be able to interpret such signals rightly.

c) camshafts vvti gears maybe be off its timing.
Check the gears and realigned, if possible.


So, in summary, your predicament, could be surmised as follows:

¶replace or check the vvti switch, or the wiring harness itself.
Check the wires before opting for a replacement

¶ check the engine oil fill port, for signs of heavy sludge buildup. if present, de sludge the system.

¶ check the camshaft vvti gears for any misalignments. Misaligned gears would trigger up the code.


PS: Never ever replace that catalytic converter or the ECU. It has for nothing to do with this code.


Pictures 1 and 2, shows a bank of the camshafts from a Sienna 2010(2gr).
I don't know your engine model though. But they ate all same principal of the vvti system.

The camshaft with the bigger "head", is the one I'm referring to as the vvti camshaft gear.

I hope this helps you sort your problem out.

I have never commented on your posts before, now I will.

Here is what I have to say, never ever stop documenting your work.

That is not the Nigerian way, but it is the way of the world which matters a lot.

Someday someone will ask you for your portfolio, if you have made it a practice to document as I have observed you do, you can easily demonstrate your portfolio without much work.

One more piece of advice...document it online outside of nairaland.

You will be glad you did.

And keep up the work.
