cel code p0330
I have a 2000 rx300 I bought it new for my wife with 20 miles on it. The only time I had a problem with it was when the CEL light came on at about 80000 miles. The car was losing power. codes 1130 171 and 301 came up. I changed both o2sensors "heated" and changed a/f sensor. worked fine until CEL came on again... This time code p0330 came up. Knock sensor....... I now have no overdrive.
One Lexus owner said the fix was to change both knock sensors as well as a new wiring harness. Another lexus owner had a new tranny installed for $5000 only to have p0330 code return two weeks later with no overdrive..
Anyone with simular problem or have a fix for the overdrive please help me
Thanks dave

Never had a similar issue, but I do remember meetya's post. Bad knock sensor and no overdrive go together (retarded timing/rich condition). In this case it is knock sensor number 2, but easier to replace both at the same time.

I had to replace my knock sensors, they are under lower intake manifold. That was the biggest job I ever done on any car. To gain access to them you need to:
- Drain all Coolant from Engine
- Remove Extension Tank
- Remove Plastic Engine Cover
- Plastic Intake Hoses
- Upper Air Box (where the filter is)
- Battery
- Remove Windshield Gator (and all motors ~30 minutes).
- Lift Brake Tank
- Remove Fender reinforcment
- Disconnect all hoses on Throttle Body
- Remove Throttle Body (~1 hour)
- Remove Upper Intake Manifold (took me ~6 hours because of that freaking rear stay bolt)
- Jack the Engine
- Remove Left Engine Bracket
- Lift Lower Intake Manifold
- Remove All Intake Gaskets (I would not recommend to reuse them)
- Remove Water Intake (next to Lower Air Intake Manifold)
- Remove Coolant Bypass Hose (also under Lower Air Intake Manifold, you CANNOT reuse it)
- Use 28mm sockets and 3-4 foot wrench to remove both Knock sensors
BTW, No O/D caused by bad Knock Sensors. I can explain tomorrow but right now I have no energy, have been working for 20 hours this weekend.
Here is your knock sensors:
Here is the tool I used to remove them:
Here is one of them removed:
Here is old sensors in my Dad's hands (he helped me alot):
FYI: Each sensor is about $200.

Anybody surprised there is a rubber hose that cannot replaced without disassembling intake system? Just imagine if it blows up!

just finished changing knock sensors
It took myself and my brother about 5 hrs to do job. spent about $450....plus gas and time. A lexus dealer wanted over a grand. I learned more about my wifes lexus than I wanted too... However there were no parts left over... were both happy. The car hasn't ran so good since i can remember..... and no cel........Thanks so much for everyones help... The mechanic at aamco need more time and $$$ to try to figure out why no overdrive... I took lex went on " club lexus "and I saved mega bucks... unlike other lexus owners that rebuilt their trannies

I had no problem taking it out. just used a small ratchet"very short". I had a tougher time getting it back in. Had to use a I believe 14mm wrench first. That bolt was the hardest job in reassembling everything.
I didn't have to jack engine either.

I had dealer replaced A/C on my RX300 more than two years ago. About a year later, the CEL turned on. Last week, it lost O/D. What dealer told me is to replace knock sensors due to the error code of P0330 at a cost of $1.1K. I wonder the possibility of knock sensor wires damaged by A/C replacement work. The car has only 58K miles on it.
Any comment is highly appreciated.
