Error codes: C1331 and C1465 (Pre-Collision System Malfunction...)

Tundra 2020
Error codes: C1331 and C1465

This error occurs intermittently, turning on and off. I’ve seen many threads, but nobody is posting a solution. I checked the wires from the left ABS sensor to the control module using a multimeter. I tried moving and stretching the wire, and it’s not loose. The ABS sensor costs around $500—is that a common problem?

What else should I check?

 

Check connector on the radar “plate” at front of vehicle.

I had this same issue and the connector was loose.

 

/\ this. I've also had crud caked up on the sensor cover (emblem) and have had the same thing. I get it coming and going for what seems like no reason, but my grill has taken a hit so I just assumed something is misaligned or whatever. It usually goes away with a restart so I haven't given it much thought

 

I must admit… it was my fault. I took connector loose when doing the genuine cooling system transmission cooler install. I thought I pushed it together.

playing around with the grill off I noticed I could reliably repeat the same error message.
I pushed in connector and heard auditable click.

that was two years ago with no issues since.

so it may be the case that it is a loose connection somewhere in that part of circuit just based on past experiences.

 

I hit that camera location above the rear view mirror with hand and its working now.. so looks like there is something wrong, its been ok for 2-3 days.

 

Error is back...

 

i get this periodically along with the trailer/towing warning, always at the same time. For lack of a better fix or taking it to a shop, I just disconnect the battery for a few minutes to make it go away.

 

Have you had the windshield replaced? When they did mine they had to recalibrate something in that system
