Separate names with a comma.
You had a loose fit between the connector terminal, and the tab on the grid. Poor fit equals high resistance which causes heat when current flows...
Just AM2 through the inverter W/P relay. That relay is triggered by the power source control ecu (on IG2D ckt) . [ATTACH][ATTACH] Posted via the...
Besides the HV battery codes, you have a whole bunch of U comm error codes. It would help to know which ecu set what U codes, and which (of the...
<shrug> If the battery temperature gets "too" high, the ecu will set a code. You normally can't hurt the fan motor by spinning it. The ecu...
Well, I've never had to take a Gen2 apart but the service manual had this to show. That's as "sure" as I can get. (The torque specification is...
Ok, those are some great questions. So the S1 upstream Air Fuel sensor is part of the fuel control feedback loop. It measures the A/F ratio of the...
If the fan and ducting are clean and functional then ignore it and move on with life. The engineers did a pretty good job designing thermal...
Hello and welcome to PriusChat! Your car has a "Transmission Control Module", an ecu (electronic control unit) that operates a motor servo on the...
Here's a thread that reviews several scantool apps and devices. Some are capable of checking codes and data on all systems of a Gen2 Prius....
That's on my 06. Whatever it is, Toyota is VERY proud of it. A new Toyota part 87200-47030 lists for something in the $650-700 range. Posted via...
I don't know what meter you are using, but it's either faulty or user error. That said, the relay in the cowl relay box controls the Coolant Heat...
INF codes are sub-codes that give more detailed information about a fault. Not every code has an INF code, but if it does you would look at...
+1 for a bad coolant control (3-way) valve. I might expect that you should find a P1121 in the ECM, but car doesn't really care about my...
Maybe it is a factor. Try a crazy bright flashlight. However, the level doesn't have to be exact, just keep it "where you can see it" - ie...
Yes, I would follow the brake bleed procedure in the service manual - I assume that there are no external leaks in the hydraulic system. When you...
Well, if it works then it works. I might look at the pressure sensor voltages for both rear brakes and see if they are the same left to right with...
The Autel is a good "capable but basic" all system scantool for a Prius. Can get INF codes. Just be aware, all of the scantools I reviewed have...
If the ICE was actually running (not decel/EV mode, injector volume more than 0), there is no way the A/F could be 4.9V. Again, around 3.3V is...
Retrieve the codes as suggested. Given the description of events, I would expect to find a "hydraulic system malfunction" code for whichever front...
If I look at that freezeframe, I would have to say "Liar-liar, pants fully on fire". Specifically, the A/F sensor is reporting about 4.0V, which...
