I had the same issue, I jacked the car and tapped the starter and started

For a RX400h having the same problem, how would you proceed with the troubleshooting? Tks for the advice.

[@sheikhselim2312]

Let me ask this, is the light for which gear it is on (P,R,N,D) on? If not, there's a good chance that the issue is resolved by doing the same repair this gentleman demonstrated.

[@felixgutierrez4806]

Does this more on the F sport model as well?

[@Jaydiyrepairguy]

It should

[@williamharris1232]

I’m thinking about buy a 2006 is 350 they say the replace the defog sensor and a week later the car will not start has 150 thousand miles on it

[@sheikhselim2312]

They told me my 08 Lexus IS250 wouldn't make it 300,000 miles and it did! It had a few hiccups that were easy to fix along the way, but was totally worth it.

[@llg7456]

Will this also make the navigation radio screen not come on? I had a bad alternator which ruined my battery so I put a new battery in the car now it will not crank. Key fob is working but won't lock or unlock doors.

[@Jaydiyrepairguy]

Have you checked the fuses?

[@llg7456]

@@Jaydiyrepairguy yes from front to back.

[@llg7456]

My mechanic got it started. He said it was like a hidden fuse under the hood like one big fuse that blew. Cost me $940 to get a new alternator and that mega fuse. But now none of the windows will go down nor will the radio work. The navigation screen comes on and the AC but no radio... Taking it back on my next off day

[@Jaydiyrepairguy]

@@llg7456 probably another fuse for the radio and relearn procedure for windows since battery was disconnected

[@niichomaclean1268]

@@llg7456can you help with which fuse it was exactly because I’m Having the same issue as you. Stereo goes in and out, sometimes the lights will go out and turn back on

[@HyrroMGFX]

By no power to the ecu does it also mean the obd2 won’t communicate with my scanner? I have no crank no start and no Obd2

[@sheikhselim2312]

probably the same issue as this, I changed the sensor he talked about, and it worked! Please give it a try!

[@Jaydiyrepairguy]

Yes

[@mgumapos7127]

I have the exact same issue, no crank no start but i have obd2 communication. Will this sensor be able to fix it?
