2001 Es300 Trac Off Light & Ck. Engine Light

Recommended Posts

Greetings,

I am new to this sight though have owned our Oyster Pearl '01 Es300 Coach with 68,000 miles since '03. Yesterday both the Trac Off light and ck. engine light came on simultaneously. This happened within a half a mile and three shopping stops right after I filled the tank to the top. I read some blogs that suggested filling way up might cause the problem, but I drove about 17 miles today which should have burned it down a little and they're still on. I've also cleaned the gas cap and filler neck, cleaned the MAFS, disconnected the battery to reset, and they still come on. I can turn the Trac switch on and off with the key in the aux. position, so the switch is okay, but Trac Off light is on all the time when running and is definetly off. Haven't pulled codes yet but wondered if anyone had any thoughts.

Seven-eight years later and I still love the car.

Thanks!

Deane

If you get a code P0330 Knock Sensors ES2000-2001

I just got done replacing two Knock Sensors. it took me 9 hours. I have replaced Parts you are going to need:

1. Knock sensor

2. Knock sensor wiring harness

3. Intake gaskets

4. By-pass hose

5. Antifreeze

Lexus quoted me a price of $224.00 per sensor. (The car has 2 sensors, if youre going to go through the trouble of changing them, change them both!) RockAuto.com STANDARD MOTOR PRODUCTS Part # KS81 $134 ea

After several hours of bothering the hell out of the parts guy at Lexus he told me that the part number for the knock sensor I needed was 896145-12040.

I ordered the intake gasket kit from rockauto.com for $56.79 this was a FEL-PRO part number MS92766 it came with all 3 gaskets. Also replace PCV STANDARD MOTOR PRODUCTS Part # V313T $3.16 and rubber grommet STANDARD MOTOR PRODUCTS Part # GV21 $2.72

Replaced wiring harness and by-pass hose from Lexus because I didn't have the energy to go through the whole mess again. They charged me $42.00 for the harness and $18.00 for the hose. The Toyota part number for the wiring harness is 82219-07010 and the Toyota part number for the by-pass hose is 16261-20010.

It took me 9 hours to change the knock sensors. It is not an easy job. Drain the coolant first. Then I removed the hood off the car. Then you have to remove the whole top half of the engine.

My best advice for anyone thats going to tackle this project is to get a small 1/4" ratchet with a swivel head. I used this to get to the intake bracket mount bolts (2), as well as the ground bolt and fuel line bracket bolt that are located behind the intake, theres not much room back there but this saved me tons of time.

You might as well change the spark plugs cause they are breeze to change with half the engine missing.

Fuel injector rail stays with the intake manifold not to be separated.
