Oxygen sensor — logbook Toyota Corolla Levin 1998
The assumption was justified (which is extremely happy!). The cause of blunting outside of VVT mode was inadequate oxygen sensor readings caused by water ingress on poorly insulated wires and connector.
Yesterday I stocked up with everything you need - soldering acid, heat shrink tubing, multi-colored wires, normal electrical tape, one-pin connectors without insulation, and something else.
In the end, everything worked out for the best. The braid is elongated, the wires are securely soldered:
All connections are sealed with heat-shrink tubing, under which the sealant is pre-drilled. The top is also smeared with sealant and wrapped with electrical tape:
Today, as ordered - very rainy weather. And for the whole day - not a single blunt! I specially chose the deepest puddles :)
Therefore, we will assume that our team won :)
ZY: While I was figuring out the oxygen sensor and its purpose, I found a sea of ​​​​very entertaining information on the topic, I can’t help but share it. Here www.gtextreme.ru/forum/sh...iewfull=1.html#post340722 is well summarized - respect to you, vergily. And a good site for auto-electronics www.autoshop101.com .
You already have 4a = is it worth it? Is the lambda on the bottom of the exhaust manifold?
I mean, you need a hole, you unscrew the protection on the right and it can be found there? (As I understood from the pictures :)
Everything, I saw :)

Blunts appear outside the VVT ​​mode, i.e. when the throttle is not fully open. Everything starts literally from 2000 rpm. The more you push the gas, the less thrust the engine has. If you fully open the throttle, then when you turn on the VVT ​​mode, the computer no longer listens to the oxygen sensor and the car gets a sharp acceleration.
To check, you can completely turn off the lambda and insulate the connector well so that water does not get in.
Listen, how did your car behave? It's just that I'm going crazy right now. suspicions are the same.
