I would inspect for damage:

• intake system
• mass air flow sensor
• PCV hose connections
• EGR valve

 

I would clean your old MAF sensor or better yet replace it. It may have been damaged in the collision. Here's some helpful info on that DTC.

 

I have a 2021 Rav4 XLE who has been involved in a front end collision. Had the intake manifold cracked from the accident I have replaced the manifold.

HEY!! I just noticed there is some sort of DAMAGE to the wiring harness connecting to your MAF sensor in your photos! That could be your problem right there. Here's some enlargements.

 

No. If one wire is cut or is broken, you will see in the MID the Auto Start/Stop icon error and a message that there is a malfunction in SS plus see your dealer message.

 

Do you have a scan tool to read live data? See what the MAF is telling the PCM...it should read around 2.5 g/s at idle without AC on, thereabouts.

 

I have the issue in Toyota,Sienna 2021/xle. MAF airflow switch replaced+venting solenoid (with OEM parts)+smoke test for any leaks . I Still not able to figure it out yet

 

hi did you solve this problem if yes then how did you solve it

 

Hello, did you solve this problem? If yes, how did you solve it?

 

MID the Auto Start/Stop icon error

there is a malfunction in SS

Yes but the MID warnings are just generic and have NOTHING to do with OP's DTC which obviously was a problem with the MAF sensor...not the auto start/stop. Also since OP's RAV was in the shop a long time for collision damage repair, his battery was probably discharged and low volts and that caused this auto S/S MID warnings. Since it was in an accident and the photos showed the MAF wiring had loose electrical tape AND the intake manifold had been cracked and replaced I think the MAF wiring or connector were also damaged and caused the DTC. Please notice the OP has NOT been back to the forum since I gave this advice--he probably fixed the MAF wiring.

Hi dear,
I do exactly have the same issue as my rav4 has been through front end accident and im having the same issue with these messages, did you figure the issue?
Please help!!!

 

please whoever see this, help me, im having exactly the same issue!!!

 

Quite often with gas model 5th gen RAVs, when there are MULTIPLE MID warnings about all manner of different malfunctions, that is a diagnostic tip off that your 12V battery is at a low voltage and failing. Either it is old, or you did not keep the cells (on an EFB) topped up with distilled water and the lead plates are sulfated. Get your battery load tested and replace it if necessary. Get your RAV scanned for DTCs so you will know if there are any other problems. If you have OPs MAF sensor issue you may need a new MAF. Check your wire harnesses for damage after that collision you suffered.

 

Friend, I have the same problem as you in my 2019 RAV4, I also had a frontal accident and after repairing everything I get exactly the same warnings on the screen as you, same code when they put the computer on, in my case I bought the original MAF sensor in the Toyota but it continues to give the same collision and brake errors, something strange because when I run the scanner I only get the code P010064 which is about the MAF sensor and no code about pre-collision or brake, were you able to find out where the problem is?

 

Experiencing the same issues. Any help?

 

Any details?

 

Troubleshooting steps

Check the intake system for vacuum leaks.
Check the PCV hose connections.
Check the PCV valve.
Check if the EGR valve is stuck open.
Inspect the mass air flow meter sub-assembly.

Also… some OBD scanners can’t access all trouble code especially OEM specific modules.

 

Aftermarket airbox was the issue

 

Wow,so shocked

 

really?

 

Yes. Replaced and no more issues
