C1440 Meaning
The pressure transducer is integral to the Hydraulic Control Unit (HCU). The pressure transducer sends a signal to the ABS module that varies in relation to the amount of pressure applied to the brake pedal. The more pressure that is applied, the greater the signal sent to the Anti-Lock Brake System (ABS) module. If a new pressure transducer is needed, then a new HCU must be installed.

 

Well my wallet doesnt like the sounds of that..
Not sure if its related in anyway but i also need to replace an abs sensor too.

Thanks though!

 

@k.strong , when you first posted the error message, the first thing that popped into my mind is the clock spring behind the wheel. I had mine go out on me last year ( lost cruise control ) I know my vehicle uses the clock spring to help with the traction control ( VCS? I think ) and to know if your wheels are straight or not. Maybe that? do you have any other telltale signs of a bad clock spring? Traction light stays on? is your horn intermittent? cruise only works when you turn the wheel 15 degrees to the left.....

I just bought the china $50 cheapo clock spring from Amazon. I figured I could replace it 4x before it cost the same as a factory one ( just like the abs sensors! lol. )


I wish I did not destroy my OEM clock spring just for curiosity. I would ship it to you in a heartbeat so you could swap and see if that was the issue.

 

Can you reset the code and does it come straight back if you do?

 

I keep thinking about this error
here is what google told me

DESCRIPTION



If the skid control ECU (brake actuator assembly) determines that the vehicle is being driven at a steep bank angle, the skid control ECU (brake actuator assembly) stores DTC C1440 while VSC operation is temporarily disabled.

This is not a malfunction if the system and sensor circuits are normal and normal VSC operation resumes.

DTC No.

Detection Item

DTC Detection Condition

Trouble Area

C1440

Steering Angle Sensor Unusual Bank Angle Detected

Driving at a steep bank angle

Yaw rate and acceleration sensor (Airbag sensor assembly)





to me ( who's just guessing here ) this points to the clockspring ( the "yaw rate" ) or the VSC computer.
there is a TW thread about resetting it, and another one about shimming the module to "trick" the computer into thinking the truck is back at factory angles.

VSC Reset

Shimming the VSC module/sensor thingy

 

Ill have to try the VSC reset. Seems easy enough to do.

 

Every 2 minute abs sensor job is one broken abs sensor away from lots of headaches and bad words

 

does this mean you snapped your abs sensor off inside the wheel hub?

if so, this is exactly what happened to me, mine was corroded in place. whatever water that got in my hub rusted the surroundings of the sensor and made it ( to me ) impossible to remove. I broke each one clean off flush with the hub. What worked for me was to find an appropriate sized punch and I think you'll at least have to pull the axle out to get at the sensor.

on a side note, I installed those RockAuto $40 sensors yesterday. no warning lights from my end, and everything seems to be working good.

Not my picture, I stole it from this thread.



But you can see it looks like its accessible once you remove the axle from the knuckle. ( picture looks to be like the bearing was removed, but axle left in place.

sorry if you already knew this, but I figured more info the better

 

Yeah snapped it clean off and i was even careful too. I put a screw in it and tried pulling it out and no luck so far. I dont have a garage so taking it all apart is a last resort for me..sitting in snowing working on the truck is not fun.

 

After a long battle i got the sensor out. Nee one is in and abs light went out right away...the only comment i have about thr cheap sensor is the wiring harness didnt "click" into place on it....but in its defence i wss beating on it to get it all the way in

 

Nice work!!
I noticed the same thing, one of mine clicked, and the other did not. I too had issues getting them to seat fully and still not 100%sure they are. Let’s hope the rubber o-ring and the grease I smeared all over it does the job

At least there is two of us who can report on the reliability of these in the future

 

Awesome to meet @Fahrenheit today and get to hear all the stories of you other guys hijinks back in the day, plus my truck looks brand new with its new tonneau

Added bonus, I got to visit a privately owned Toyota graveyard down by Martock, chatted with the cool dude who owns it and picked up the footrest my truck has been missing since I got it. Score!

 

@Canoehead , I told him about us doing Pipeline, you on stock height and nose-diving your truck into the ditch on Muddy Myra after @TacoMitch93 went through in his, good times boys!

Cool. I think @D2. met the same guy today!

 

We need to do this stuff more!

 

I agree 100%, I'm working in it! I'm not really a fan of winter wheeling, too risky, but soon I'll be up And we may have to set up a Valley run, we did an awesome run New Years day just south of Berwick

 

It was the guy selling the red single cab (cab only) on kijiji. He's got a bunch of old Landcruisers and a couple of tacos (among other things). I was late to meet Garth and had the boys with me so I didn't ask him what else he had around but I might see about getting some wiring looms off him if he's got any spare. Think that might solve my 4x4 light flashing.

 

I have an 11 dollar ABS sensor from China lol works great!

 

I had to pressure wash and dry my carpets in the boiler room for like... 3 days after that swamping!

 

More pictures from the same day!
