Separate names with a comma.
No schraeder port on a Prius. You would need a gauge set that has the correct adapters to fit inline between the fuel rail and the supply line....
I would replace the pump with a Toyota part, flush the inverter cooling system while you're there (be surd to bleed the system- can take 5 minutes...
What are you using to pull codes? P3102 sets in the Hybrid Control ecu. It should have 1 of 7 INF sub-codes that would help narrow down the...
Well, it's POSSIBLE that the LED itself has failed, but really unlikely. I would want to make sure that power for the right turn indicator is...
It COULD be a vacuum leak, but that would show up as high positive fuel trim numbers only at idle. At cruise and on acceleration fuel trims would...
Torque and Dr Prius are useful apps but both are very limited in what they can do. You might consider getting a more capable scantool (whatever...
If "everything is working" (correctly), then the ECM wouldn't be setting that code. The ECM doesn't care about what you see with your temperature...
You will want to use a capable scantool to check all 15 (or so) systems on a Gen2 Prius. Here's a thread that reviews several scantool apps and...
Top of the list is that your throttle body bore and MAF sensor have "normal" buildup of deposits that form over time. The ECM compensates for this...
Hmmm. If you need to refill the brake fluid regularly, where is it leaking out? .
<shrug> It's your money, you can spend it as you will. You can fire the parts cannon if you want. Here's a thread that reviews several scantool...
I don't know. You don't know. You won't know unless you do some testing. Could be the pump. Or the valve. Or hose routing. Maybe the tank is...
I've said it before and I'll say it again. Monitor the data and see what the system does. Run the car up to full operating temperature. The next...
First idea - you could have a faulty ignition coil causing a misfire. Idea 2 - you could have installed a bad spark plug - always a possibility if...
Are you sure the MAF is plugged in correctly (or the connector isn't damaged?). What does the MAF sensor read under different conditions? What...
Toyota and Autel both assume that whoever uses a scantool and repair data is a trained technician. The data in each system only makes sense when...
Dr Prius is handy for viewing "live" battery data (it can also datalog to a csv file). I got a BAFX products device - has worked fine for me. If...
When there's a problem with the hybrid drive system, it usually winds up disabling regenerative braking. So the brake control ecu turns on the...
So the parking motor consists of 3 stationary electromagnet coils. The ecu turns them on & off in sequence to act on the rotor (which has...
Well, the inspection system is designed to prevent people from "just getting through emissions". The ECM runs several tests (called monitors) that...
