Question about 2005 Toyota Highlander

Catalytic Converter Replacement Repair Cost

The VSC, Trac and check engine lights were on in my wife's 2005 Highlander, and when I took it in, it got a P0420 code and was quoted $495 in parts and $150 labor to replace the "Bank 1 Rear Catalytic Converter" - wondering if this is a reasonable price for this job in California. Thank you

Code p0420 refers to catalytic converter system bank 1 --efficiency below threshold ===causes -- catalytic converter ---wiring---HO2S 2 sensor
The cheapest part to replace is the HO22S sensor so I would do that first. Bump the cat converter soundly with the heal of your hand and if it rattles it needs replacing as it will be cracked internally. Dismiss any tinny rattle as that will be the heat shield loose
The time taken to replace both in an accredited shop will be less than 1 hour so it may pay to shop around and compare prices on the converter and labour costs.

VSC, Trac off, and check engine lights are on


I took mine to the dealer to find out why the VSC, Trac off, and check engine lights are on. They said it is the camshaft position sensor, it retards the timing, and causes it to lose power when climbing. Also, 1 of every 30 to 50 scions have this problem. Sounds like it should be recalled for this. The cost of replacement is about $500 bucks. Get your dry belts and valve cover gaskets changed at the same time to avoid labor charges later. I couldn't believe the dealer charges $89 bucks an hour for labor these days, Rediculous. At least it comes with a a 12 month unlimited mileage warrenty.
