Separate names with a comma.
Calculated load was originally "current airflow divided by peak airflow"(with BARO correction). Google says that the car makers used different...
According to the wayback machine, DoctorPrius.com was a mobile (refurbished) HV battery installer in the Washington DC area. Posted via the...
R8 is the ABS MOTOR relay (1). That's what the ecu tries to use for normal brake operation. When the ecu turns it on, it should connect B+ power...
If you have Techstream, look at the code list. If there's a snowflake symbol next to a code, then click on the symbol (that's FreezeFrame). The FF...
When the engineers design the ICE, they measure all the sensor inputs (everything except the Air-Fuel or O2 sensors) while figuring out how much...
As mentioned, make sure the brake switch works. What scantool are you using? DrPrius is handy but is very limited. I would use a capable...
A common problem is a water leak that runs down the inside of the body to behind the wheel wells. The source is cracked seam sealer around the...
So, there are two relays for the brake actuator pump. Both just supply power to the pump motor when the ecu turns one of them on. The pump pushes...
I would expect you have to clear the code from ecu memory. .
So, the description for C1253/138 says that the ecu didn't see the correct voltage (more than 3.5V) on the MTT feedback ckt when motor relay 2 is...
Do you know if the mechanic cleared the code before trying to bleed the system? (won't bleed if you don't). Did the other rear brake bleed...
What about the actual carbon canisters - are they installed or did you delete those? Where does the fuel tank vent go? Posted via the PriusChat...
Here's a graph from my 2006 during a cold start (using a different scantool). From the left, you can see CHS (tank outlet) and ECT go up about...
Hello and welcome to PriusChat! My response to any CHS system faults is to ask, what does the SYSTEM do? Does your pump run when it should? The...
If you have a wiring diagram then you should measure voltages at the left and right side steering wheel switch assemblies. There's three wires....
I used different chargers back when I did DIY. I recall disabling the delta V setting, and just charged a fixed (7500?) maH amount at 1A. Let the...
There's one or two threads about it somewhere. The Prius 1.5L uses a "psuedo-Atkinson" cycle - high static compression with later than normal...
I am only familiar with those as specifications for VW-Audi coolants (there's G12, G12+, G12++, and G13). .
Cut-off wheel and torch will burn the rubber (and it will stink - oh well). Watch where you aim the torch, don't want to burn the brake hose or...
I would clean the throttle body bore and blade (also clean the MAF sensor), then drive the car while monitoring short and long term fuel trim....
