As subject refers, my Sienna throws the codes below- P0016, P0037, and P2716.

The car doesn't accelerate well and when slowed down finds it difficult(takes time) to pick up. I also observed that the fuel consumption is high. A mechanic said I should change fuel pump and filter.

Please gurus, kindly advise me. Thank you

Your gear is having issues. This has nothing to do with fuel pump. Did you ring the car recently?
What work did you do on the car in the past few weeks/month ?

Oxygen sensor before catalyst is bad.change it.....
Camshaft..did they open engine or ring it.

I got the car Nigerian used and mechanic certified it okay🙂. Na wa

You are supposed to test drive it and see for yourself.

The car gearbox is about N700k with oil and installation cost.

That P2716 code shows it all.

Again, maybe a 10pin gear has been installed instead of 13pin.

Terrible news I feared to hear. Well, I went with a brother mechanic who drove it and confirmed it's okay before I paid. Well I see it's now my cross to bear.

How do I find out it's 10pin instead of 13pin gear that was installed? I need to start sorting out the car. My cross to carry 🙂

I appreciate bro. I'm around Isolo Lagos. Oga Gazzuzz seems more into sales these days🙂. Autologic has been a bit quiet. Will try reach out those men and see how it goes

From my little read up, it's saying changing Solenoid D under the gear. If this is possible, do I still need to change the whole gear? I'm not using the Sienna for trans but for moving my fam and maybe a travel to the East once a year

Gazzuzz said he's no longer servicing cars, autologic is out of the country atm. My search for an automobile workshop continues in Lagos.

So I met a competent engine mechanic at Ajao and he corrected all the faults in the engine and the P0016 code is gone, remaining the P2716 and P0037.

Thank you all

I'm glad that you seem to be making a headway here. I also have some issues with my 08 LE. Could you give me the contact of the mechanic? I sent an email

Thanks Chief for quoting. I resolved code P2716 last Friday. An electrician found out that one of the connector pin in the harness of the gear connector was rusted. He changed the pin(connector), voila code is gone.

For P0037, I have changed O2 sensor still no show. I'm tired of ladipo guys. When I rest small, I will face it

Is the car moving well now? Is the gear issue still there ?

Yes there's improvement. The only issue that's major to me is the abnormal revving I experienced if the AC stays for long in the afternoon, causing the oil light indicator to be blinking. If I off the AC, the car will normalize. Don't know what's causing that?

Oil light blinking is related to sludge in engine, failing oil pump. This is an engine issue. Try check to avoid issues

Truth is there. The mech that set the P0016 code suggested opening the oil sump and checking the filter. I will address this in my next oil change. Thanks a bunch Chief.
