Don't worry about the solar sensor circuit. All Lexus cars have these codes, even the brand new LS600hl. Plus, you can't clear the codes. Just ignore it.

Sorry, I didn't see the P505 Idle control circuit. Most of the time this code mean your throttle body goes bad and won't idle.

Wow, i completely missed that too. Nuum is right, usually its a bad throttle body. The little motor that controls the throttle blade goes bad sometimes. Unfortunately, a new throttle body is $1000+...

Solved the P0505 idle control system malfunction, it was also giving idle problem while AC is on and car on Parking gear (P). It was just all about cleaning the throttle body by cleaner.

Great tip! I didn't get a P0505 but did get tge B1421 & B1424 solar sensor codes. I will clean the Throttle Body and see if this solves the irratic idle speed. Thanks for the info.

if you pull these codes in a darker area like inside a garage, that may throw them. clear the codes and do the check in the sunlight.
