Toyota celica engine light after driving through puddle.

[Grahamr123]

I was driving back today in the rain, went through a few puddles. A few miles from home I noticed my engine light was on, as well as VSC and TRC OFF.

I got the error code with a bluetooth ODBII reader and the Torque app and I got back P0411 (Secondary Air injection system Incorrect flow detected)

Can anyone explain what this could possibly be?
Thanks!

Let it dry out and clear the codes - bet its a water induced temporary blip - problem will disappear but obviously the light will stay on until the ecu is cleared of fault codes

Yer, I'm going to wait till tomorrow and check again to see if its still there. I assume getting the code cleared is something that only a garage can do.

Depending on the year of the car, most obd2 readers can erase codes - if not you can buy them quite cheap on amazon

If it's water / puddle related, then I might suggest that the first port of call would be to look at the plugs on the wiring and sensors that relate to the fault code?

It may well be that water has got into the plug.

I've had a couple of similar things recently.

First was my Skoda - same as you, was driving on a very wet day, presently the ABS / Traction control lights came on. Next day, I interrogated the ECU and it pointed to a fault with the nearside ABS wheel sensor.

Removed the wheel, and saw that at some point in the car's history, someone had cut / torn / damaged the wiring to the plug, and crudely soldered it back together, using insulating tape over the repair. Removing the tape saw the wiring crumbling to dust from corrosion. A new plug and wiring soldered on and sealed with proper heatshrink tube sorted it.

Then I had a Peugeot that developed a fault on another wet day - the radiator fans came on at full chat and stayed on. I eventually had to remove the bumper on that one, to find an electrical multiplug behind it that had eventually allowed water to ingress it and the pins were green with corrosion. A good clean-up job, grease packed around the rubber seal and the whole thing wrapped in tape sorted that one out.


I would start checking the wiring around the fault and pulling plugs to check inside each one. You may well find one full of moisture and / or corrosion.

On my Ovlov you can clear fault codes with the android torque app?

I too had a Peugeot that developed a fault on a wet day. A bent conrod!

Lol, oops!

I did that to a 4.0 litre six-cylinder Jeep Wrangler whilst off-roading once. Went through a huge depression full of water, that came up over the bonnet... beginner's error!

It stopped dead, and wouldn't turn over on the key - engine full of water!

I removed all the spark plugs (this is in the middle of Salisbury Plain on a wet winter's Sunday afternoon - not fun) and cranked the engine on the starter until most of the water had been spat out of the plug holes (and at first, without exaggeration - it was shooting up around 3 feet out of the plug holes like a water pistol ).

Replaced the plugs, turned the key, and vroom! Back in business!

Did an oil and filter change once home, and drove it around for another year. It was never QUITE as powerful as before, but not enough as to be that different enough to bother pulling the motor to bits. It certainly still started on the button, idled beautifully and drove as near as dammit perfectly - no misfires or hesitations.

I then sold it onto a mate. He also drove it for a good 6 months, until one day - BANG! Number one rod let go, and made it's presence known through the side of the block...

He tore the motor down, and found one well-bent rod, that had been like this for 18 months since I did the damage. You could see by a witness mark in the barrel that the piston had been going up to the top of the bore but stopping short about half an inch from the top for ages, because of the bent rod

Amazing that it ran so well for so long with such a badly bent rod. Testament to big, heavy, agricultural Jeep engines. And your story being testament to ropey, weak, built to a budget French motors I guess??!!

I started the car again this morning and the fault code was still there. I cleared the code on the torque app and took it for a short drive round the block. All seems fine, it hasn't come back yet..

Fingers crossed its just a blip.

It came back today!

It was just as the fuel light came on too, about 10 seconds after. That may be pure coincidence though.

Anyone had error P0411 error code before?

Hi

Could you let me know where you got your reader from ?

I smashed a huge puddle (aka lake) in a vectra once.

Engine light came on and off for about 2 weeks then sorted itself out.

I found that one of the air pipes came out of a little bracket that held it. I put it back and the light hasn't come on since (Fingers crossed)

When I swapped the steering wheel on a T190 the "VSC and TRC OFF" lights appeared. It is because the new after market suede wheel does not have indicator self cancelling connectors or something, according to the techs. I think the ECU gets confused when something is missing. Odd, but there you go. I also had the airbag light on too, so nearly a full set. So could yours be something to do with the steering connections, rather than water under the car? Maybe worth a check.
