ABS/Traction light C1405 and C1445

[bcool]

I installed a spacer lift on my wife's 2015 limited. I must have messed up a speed sensor, has anyone had these codes c1405 & c1445? I tried to reset the codes with an Oreily's OBD reader with no success.

Is there any easy way to trouble shoot which speed sensor it is? Or to determine that it is the sensor and not a loose connection?

Any help would be appreciated. I did try a search first. I am located in N. Utah if anyone knows a good indy shop. Thanks in advance.

I just threw the same codes. I think the Toyota Tech Stream tool will tell you which corner the issue is at. Without it, it's just a warning. I'll report back once I get info back from my tech. (15 Limited here as well).

From the repair manual:

C1405 Front Speed Sensor Right
C1445 Steering Angle Sensor Intialization incomplete

C1445 Detection condition:
Steering angle sensor zero point calibration cannot be obtained when the vehicle is driven without a record of steering angle sensor zero point calibration at a speed of 36 km/h (22 mph) or more for 30 seconds or more without the brake pedal being depressed.

Possible Trouble Areas:

• Steering angle sensor (Spiral cable sub-assembly)
• Yaw rate and acceleration sensor
• Master cylinder solenoid (Skid control ECU)

I'd do the calibration first and see if that fixes it. Sometimes one thing throws other codes for no reason.

This is very helpful info.! Thank you so much. Let me know how yours turns out! I am scheduled to take mine to the dealer next week.

Were you able to troubleshoot this by yourself? I am replacing the sensor wire tonight. Thanks.

Yes. I had tore the wire clean in 2 lol. Luckily it was available separate from the sensor. The older ones are one piece.

cant clear my C1445

I cave C1445 - my issue was from replacing the clock spring I bought this exact one https://ebay.us/m/WiGLta and watched this YouTube https://www.youtube.com/watch?v=dSNuu6adIT4 for my tutorial. It's been about a year and everything is fine except the traction control dash light came on and hasn't gone off. I tried to jump the OBD connector using metal wire in ports 4 & 12 - 4th from left on top and 4th from left on bottom. I did the zero calibration reset I saw online and it's just not working. Any ideas? My garage gave me a code of C1445. I really dont want to take this to Toyota because it will cost $1000. My next thought is to buy a scanner and try to reset it or get an OEM part.
