20 Most Recent 1999 Lexus ES 300 - Page 9 Questions & Answers

Below are some pictures for you. I will give you a hint incase you don't know. If you look at the botom picture, it shows you the tensioner. You will want to push the rod until you can put the hex wrench through the hole to hold the rod. Then install the dust cover. When put the tensioner back on you will want to alternate back and forth on the 2 bolts so it's good and even and then remove the hex wrench. Hope this helps and good luck.

Hi there Amy:Check this for 1999 Lexus ES 300 3.0 liter DOHC V-6 (1MZ-FE) firing orderHope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using Fixya, and have a nice day.

Before servicing the vehicle, refer to the Precautions section. Remove or disconnect the following:Drain engine coolantV-bank coverAccelerator cableIntake air connector Throttle Body Upper and lower intake manifold assembly Rear water bypass joint Water bypass pipe Water bypass pipe from the water pump Wire clamp from the bracket on the water bypass pipe O-ring from the water bypass pipe Water bypass pipe bracket from the water bypass pipe 2 bolts holding the starter to the cylinder block Starter connector Starter from the cylinder block Nut, and disconnect the starter wire StarterReplacing a starter on 1999 Lexus ES300 was not all that hard. You had metric socket and combination wrenches and a phillip's screw driver. In this video show you how uninstalled the starter and then replaced it in pretty good detail. This starter is used in 1998 to 2001, and so basically you could use the same procedure that is shown there.Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using Fixya, and have a nice day.

need to scan computer before you do anything else.

Hi sorry to tell you but it is NOT a switch :(
What it maybe though is the "Bands" sounds like they are slipping, they simply may just need tightening, this is NOT a task that one can DIY. if it is this it isn't too expensive a fix either.
You will/should take the car into a place that specialises in the Lexus model. then ask ONLY for a "Quote' as to costings and what needs to be done, get appraised of it all, and go from there.

I would suggest you watch some YOU TUBE Video
on that subject & try & find your exact vehicle on that site.

It is a good place to go for an education

Its a Oil Control Valve most likely. Get the valve. Its like 100 from Lexus. Mine did the exact same thing with that code. GS300

im pretty sure it has only one. most vehicles do!

Yes, when you turn on the headlights, the parking lights and taillights should also come on.

hi, this is an obd2 trouble code table, it can help you understand the code.

Basically the engine is either at rest or cranking when the VCM (PCM) is monitoring for the high voltage diagnstic.
The PCM has an internal 5 volt reference that's used for several circuits. This voltage is dropped across a resistor and fed to the corresponding control circuit. The BCM monitors this voltage to determine circuit integrity.
You could have a wiring problem between the PCM (ICU) and BCM, or a problem with the connector(s) at either the PCM or BCM, or the BCM is going bad.
For this problem a wiring diagram is your friend. You can check the connectors for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection, or rubbed through wire(s).
Check the PCM to BCM wiring very close.
A good way to find a wiring problem is to clear the code. Monitor the reference voltage while having someone pull on wiring at the BCM/PCM and wiggling the harnesses. If this makes the voltage to go high you know it's a wiring problem. If the voltage remains constant and the code RESETS than the VCM is the problem.

If you are sure it is charging with a light load, and the alternator is new, then the only thing I can think of is that the belt is slipping. I'm not certain if this model has an adjustable belt, if it has a single self adjusting serpentine belt then I'm out to lunch. If the alternator uses the same belt or has a common pulley to the A/C pump, then you have likely found the problem.
