Glorified Toyota

Hi Peter, If you are to replace your O2 sensors I would suggest use OE but nothing else. What some of the mechanics do is to go for an aftermarket, pay less and still charge you the OE price. You are likely to have problems with an aftermartket O2 Sensor unless it is a genuine Denso or NGK or Bosch. Denso or NGK O2 sensor/sensors is what I would use on Lexus. Since the begining of last year, I came across with a company called SPARETO in Estonia where they have a fantastic service (good old fashion service) with speedy delivery using DHL (usually less than a week). I deal with a smart engineer called Viktor at SPARETO. I would contact them with your VIN and see what they suggest for O2 sensors. They are prices, including delivery, in most cases, is minimum 30-50% less than what you would pay locally. Another place is Rock Auto in the US or LexusPartsNow in the US. Hard to say which O2 sensor/ sensors are faulty (Pre or Post catalytic convertor). Scan should tell you which when the CEL (Check Engine Light) is on. If prices are reasonable and it is the pre cat O2 sensor it may be advisable to replace the one on the other bank. These have a bearing on fuel consuption more so than the post catalytic convertor ones. Post cat ones are usually for emmision control. Average life expectancy for the O2 sensors is around 180,000 KM's. Pretty much similar to that of a long life premium irridium spark plug. I hope this helps and GL.

IS250-2007 Have it properly diagnosed by Lexus, before you let some of these so called experts start replacing solenoids or even tranny. Have you had the tranny serviced using genuine Toyota WS fluid and original Lesus/Toyota tranny filter and gasket ? If you haven't, that is something to consider before anything else. I have had that done at a Lexus dealership. And I am glad I did it. For general service, I use my own mechanic. What would Lexus charge you for diagnosing the fault ? You may want to ring and ask. At least you will have some direction to follow thereafter once it is properly diagnosed. I am not suggesting to get it repaired at Lexus just diagnostics no more to start with. After that what you do, where you go is up to you. What controls the solenoids is the ECU. It may be a faulty ECU as simple as a dry solder joint in the circuit that drives the solenoid. But Lexus guys should be able to tell you the source of the problem/remedy and the cost in rectifying it. GL

No, I don't for 2005 ES300. You may want to ring any Lexus dealer and ask them.

Steve It may be UR tranny. But these transmissions are solid as a rock ! You said "Yes I did the scan and cleared the code by pulling the fuses. The code came back." You can't erase the codes by pulling fuses out ! You need a scanner to excetute that. If you used a scanner and error codes re-surfaced soon after erasing them, obviously there is a problem/fault. Most common problem may be a glitch causing the the ECU to throw out codes on these cars. Here are the DTC examles of what I had few years ago with the GS 300 P0751 SHIFT SOLONOID ‘A’ PERFORMANCE OR STUCK OFF. P2714 PRESSURE CONTROL SELONOID ‘D’ PERFORMANCE OR STUCK OFF. P0751 SHIFT SOLONOID ‘A’ PERFORMANCE OR STUCK OFF. P2714 PRESSURE CONTROL SELONOID ‘D’ PERFORMANCE OR STUCK OFF. Having worked on these ECU's in the past, what I found is that, CLEARING the DIAGNOSTIC TROUBLE CODES and RESETING the TRANSMISSION ( Transmission control is part of the ECU and it is not a seperate control unit here) more often than not fixes the problem. In my case it did. If in your case, if it is a mechanical problem to do with valve body, solenoids or other, than you would want to get that correctly diagnosed. Your best bet is likely to be the dealer. As for the repair, once the correct diagnossis is on hand, it will be up to you where to go. GL

Not necessarily be the O2 sensors. Fuel related issues can throw out DTC's ( Diognastic Trouble Codes) which may indicate lean/rich fuel mixture. I would throw in the fuel tank top quality Fuel Systsem Cleaner/Conditioner prior a fill up with Premium 98 Octane Fuel ( Liqui Moly Fuel System Cleaner Conditioner ). Autobarn, Supercheap Repco sell this stuff. See how it goes B4 starting to replace O2 sensors at that ridiculus cost and potentially getting no positive outcome. Fuel pump/Filter is another thing which I would look into. You need a scan tool or someone with a scan tool to read and erase the code prior addind the cleaner and re-checking it after. GL Bro.

Steve see the last post on this. Use a scan tool clear all error codes/diagnostic trouble codes in the ECU and reset AT (Automatic Transmission) using scan tool in order to learn new driving pattern. Your problem likely be solved. Merry XMas.

I have used Brembo pads, Brembo P83072N for front & P83073N for rear, which comes with a brake paste and anti squeal shims with 100% success in eliminating the noise issues with the brakes. GL

Any trans related problems, with these cars, first thing to do is erase all DTC's and reset the ECU with a scan tool. This should restore the full operation of the ECU and clear any glitch which may have occured for whatever reason ( software glitch within ECU or other). If you are a member of NRMA or RACV or similar roadside assist in your capital territory, they should be able to do this for you if and when a call-out is requested using a scan tool through the OBD connector.
