Separate names with a comma.
In addition to what Brian said about your scantool, I'll make these observations about the codes you posted. These code are from the TPMS and...
Carbon at the tailpipe is a bad sign. Firstly, your engine is (or at least was) running poorly (producing too much soot) and secondly, the CC was...
This may be true for you, but as time goes on and the used battery stock becomes older and weaker, it will be less true for others. This one...
This process will do nothing useful. There is not enough potential difference between the modules to move any meaningful quantity of electrons...
... or a state that adheres to CARB standards.
It can take a while for the hybrid system to recalibrate to the best economy after a 12 V battery disconnection. Maybe up to three tanks. Also,...
Those copper-core plugs you mentioned will be only good for 20,000 miles at best. It might be interesting to see what they look like now....
Yes you can, but it must be halogen not HID or LED. You use both high and low-beam circuits to draw the highest current.
What ChapmanF said in post #5.
I think you're missing something. You do not need to press the unlock button on the key fob and I'm surprised it does anything useful for you,...
More than likely a loose connection at the 12 V battery or the negative connection to the car body. Check all three connections are clean and...
The way the Dr. Prius app graphs the block voltages exaggerates the difference. You only have a 0.22 V (which is not the best) difference between...
In reality, just starting it for five minutes probably does more harm than good.
What does "switching to "B" mode" do, in this scenario?
One thought I had was, what was the code when you rescanned the car? Or did you assume it was again a P1121? Incidentally, DTCs are 5 characters...
I think you will find it is the other way around, and that certainly is what happens in a Gen2. That is, the indicators flash at a faster rate...
It is likely a JDM import. It seems very popular to import JDMs into Pakistan.
This reasoning is not sound and any conclusions you draw from it are invalid. I'd be very suspicious of any 'professional' who spun such BS....
The only thing that might be "identical" is the symptoms. Unfortunately, there is a myriad of different problems that can produce these same...
This sounds quite normal for the Gen 2 from a cold start. Read the Hybrid Warm-up: 5 modes of Prius Operation. in my signature below to...
