Lexus RX300 Engine Coolant Temperature Sensor ...

Incorrect pressure caused by incorrect grade of fluid comes straight to my mind.

seems like parasitic drain. use a dc clamp meter to measure the drain, pull fuse one by one to identify

Hi, The first thing to do is take off the hub caps & see if one or more wheel nuts have come off! If that is not the answer then check if one of the brake pads has come adrift. The only thing easy left is the wheel bearing, should that not solved then you have a half shaft problem and you need to take that out look at the teeth on part that goes into the Diff the teeth should be straight if not then you need new half shaft & if one has gone you can be assured so has the opposite wheels well on they way to going or your Diff needs renewing & thats expensive. Please leave me feed back: Malcolm Campbell, Thanks.

yes

The minimum compression required is 95 psi, below this there is no good combustion, incusive the spark plug gets wet in gasoline If this condition exists, you should check the piston rings and cylinder surface

YES, you have to investigate what is throwing your valve timing off. That could be anything from a vacuum leak to clogged injectors, bad plugs, sensor ect. Have the car analyzed to find the cause. There can be many causes. Good luck

Check the Earth cable in the boot see that it's clean no white bits around the connection or the join. Cheers, Malcolm Campbell.

You will need to remove the clock and have it repaired.

Could also be the O2 sensor. Wiring comes into play also.

replace the stereo

Tank holds around 70-75 Litres and has a range of around 480 Kms. Obviously that depends on engine condition and the weight of your right foot. Don't take any notice of the readout telling you how far till empty, it will still keep going when reading 0 Km, just don't risk it too long.

check the brake fluid level in the master cylinder. if its low it will turn on the brake warning light. top up if low and make sure the light sensor float is moving freely. then check the e-brake switch and make sure it is in the fully off position when the e-brake is fully off. its usually one of the two that turns it on. have you check for a brake fluid leak. if its has ABS it could be a problem with the hydraulic unit however the ABS light is usually on at the same time.

Call any auto parts store and tell them what you have and they will tell you the gap setting

Knock sensor controls ignition timing. It should have no control on transmission shifting. Did you disconnect/remove anything else to access the knock sensor? Was the battery disconnected? If so, a relearn procedure may be required for trans module etc relearn shift points while you drive the vehicle

You have a bad ground wire somewhere; probably right off the drivers side door. It may be difficult to locate because all the window switches are wired to the master control switch on the driver side door. I often find the wire breaks somewhere in the conduit between the door and the dash. All the opening and closing of the door damages the wire, particularly when the wire doesn't have any room to flex. Once you find it and bypass the broken connection all the switches will work. Start with the connections on the switch and work your way to the dash. You probably can find a good YouTube video that can show you how it's done. A multimeter will be very useful checking the continuity of the wires. I like to disconnect the switches in both the driver and passenger doors. I will then use a piece of wire to bridge the connections on (passenger) door connector, or ground out to the vehicle body. You can use the multimeter probes on the driver side connector to find the broken connection without tracing the whole wire harness. There should only be one hot wire that is supplied with power on the drivers side connector. Use the multimeter to find the hot wire first, using the vehicle frame as the ground, and then ignore it. Once you find the color of the wire that's broken you can just follow it along the wire harness till you find the break.

take it to jiffy lube

not sure but I will say this. most timing sets should be changed every 75 to 100k miles. its cheaper to change the belts and water pump then to pull the motor and spend thousands on 10 dollar bent valves

try running a tank of fuel with an addative in , get one that covers the catalytic convertor as well as the valves' injectors etc , take for a long drive at a highish speed to get the engine to a good working temperature , you may have to repeat this a couple of times but should help with the fuel consumption at the end of it

Depend which side, if you tell me that i will let you know.
