Question about 2008 Lexus ES 350
2008 ES350 70,000 miles; gently driven and well maintained. Engine light on (with other lights too), car runs and purrs perfectly however. Took it straight to Lexus and was told the timing was off of the valves and cam gears causing engine to detect error code. Would need to replace cam gears. Erased codes for now. $4,000.00 to $5,000.00 estimated job when needed. Hard to imagine that this would be the case for this engine built by Toyota and rated as one of the most bulllet proof ever made.
Sounds like a timing belt issue. Toyotas will run forever if you change the timing belt every 100,000 km, or 65,000 miles

chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)

SOURCE: Check Engine Light came on with code p0420. Dealer wants $3900 to fix "b2 manifold and front pipes. Does this make sense. Are their better alternatives. I left the dealership without fixing it and the

yes its related to knock sensor because car is running rich in fuel, and car runs of on safe mode, so overdrive will be off. have you and a friend replace it. remove intake assembly, then intake manifold, but first remove your anifreeze from radiator, trust me you want to remove antifreeze! their are brackets by the fire wall to hold down the manifold, thats the hard part is taking it off and putting that on since not to much space to work on it. on the block you'll see the two knock sensors, has 2 wires each, knock sensors cost between 150- 200 a piece, still cheaper than dealership putting it on. also buy some liquid gasket because you will need that. after putting it all back together reset the ecu and you should be fine,
