06 overheated P0117, P0327, P0332

My 2006 Sienna started making a funny clicking noise but I couldn’t safety pull over for another half mile. When I finally did it was overheating steaming like crazy. The oil and coolant levels seem okay but it’s throwing codes P0117, P0332, and P0327. I’m afraid my engine is fried. If the engine gets hot enough to break the block sensors is it worth fixing?

Overheating aluminum heads is nearly always bad. However, the fack that it was steaming suggests all hope is not lost. If you sprung a leak that dumped coolant on the outside of the engine, it may still have provided enough cooling to have saved the engine. I'd guess you dumped coolant on the knock sensors/wiring and caused your codes. Fix your leak(s) and do a check for exhaust gas in the coolant. No gases or oil in the coolant and no coolant in the oil plus no overheating and I would be confident to fix whatever else is causing the codes, if they hang around.

I would still check for exhaust gasses in the coolant. I think you can borrow a tester from the auto parts stores from their tool rental (pay for it, use it, get your money back when you return it) program, but they are typically only about $35 if you want to buy your own. You'll still have to find your coolant leak too, of course. Glad you didn't (it would seem) cause any permanent damage!
