Hello from Michigan! Heres my I've noticed an exhaust leak between 2 pipes and since then I have no boost showing on my gauge and no power also. Then to top things off my accidently reset my Apexi SAFC back to 0s and now running real rich. I'm a disabeled vet and my family and I just moved here to Michigan and my ol'lady 2 kids and I are living off my VA and disability benefits so cash is tight right now. My question is is there anyway someone can help me with some numbers for the SAFC to get it somewhat close so it can be drivable. And any ideas on the lost boost no power issue. I'm gonna fix the exhast leak and do a boost leak test but could it be anything else. I did get into the throttle pretty last week and it ended up shutting down on me and wouldnt start back up till the next day thnats when the no boost no power was noticed and exhaust leak was noticable worse.Also when me buddy reset the SAFC. How or why is beyond me. I've been told a bad wastegate and a boost leak. PLEASE HELP. Heres pics and a list of what I'm working with.

I have three error codes on my 2001 RX 300: P0330, P1135, and P1155. I know that this is the knock sensor 2 circuit, the air fuel sensor circuit, and the A/F heater circuit. Is it possible that there is an underlying problem that could cause all three codes to show up? I had to replace a catalytic converter, and my car locks out the overdrive intermittently. The mechanic wants to replace all of this stuff, at a cost of

I found a Lexus RX300 diagnostics repair manual online at bio.souz-96.com/Lexus/RX300_Repair_Manual/.../Diagnostics.pdf

What these codes have in common is the wiring harness or the ECM could be the problem.

Hello, looks like you've got a couple things going on there. For your 2001 RX300 these are actually common problems that I've seen through out the years. I'd say go ahead and have the A/F sensor replaced, its usually the bank 1 (firewall side) sensor 1 (pre cat). Knock sensors are pretty common as well, I'd clear the code and see if it comes right back if so time to change. For that job you should replace both knock sensors and the sub-harness connected to them. Let me know how it goes

Hi, any have this problem? battery drain 2002 gs 300 sp. deisign ecu b1 circuit. when ecu b1 fuse is pulled drain goes away. how do I isolate the problem. Thanks

PrimeJutsu

Is that the only fuse that will make the draw go away? If so then your gonna have get a schematic of that circuit and locate all the components powered by that fuse. BTW Any aftermarket parts installed if so start with those.

I bought an sc400 and the headlights dont work at all they dont want to turn on idk if ita a bad fuse ir some bad wiring or the headlights are bad

Thanks, PrimeJutsu. I've just had the O2 sensors replaced. We will see if that makes the knock sensor problem go away. If not, $$$$$$$$$$$$$$$44

I was driving the car on the highway when it started to bog down.
the engine light started flashing.
I limped it to my garage and there it sits.
