Inverter Pump replacement - Looking for Local mechanic in Orange County, CA

Sounds like it could be the A/C evaporator temperature sensor (thermistor). On some cars you have to remove and split the heater-A/C housing to get to it.

That's the rub, isn't it? The industry reward technicians who can "turn a wrench" and change parts quickly. But diagnostics is what can separate a really good shop from an average or lousy one. Which part needs to be changed? Is it a parts failure or a wiring fault? That is where costs for equipment and training go way up. That and the fact that very few technicians have the skill set to do diagnostic work well.

I will agree that any expensive shop isn't necessarily good, or that any inexpensive shop is bad.

If you have a shop in an area where you can specialize completely in a niche market (such as Prius repair), then great. If you "like" the work your guy can do for the price he charges, then good for you. If he has loads of work and can make a living above what his operating costs are, then good for him.

Me, that last inverter pump I did was like this: Scan vehicle for codes. Check all underhood fluids for level and condition. Confirm lack of coolant circulation in coolant tank. Confirm lack of current draw through pump circuit. Confirm adequate power and ground supply at pump connector. Drain coolant- noting white "silt" contaminants- (precipitates). Flush cooling system with water. Replace pump. Refill system with new Toyota coolant. Bleed system. Pressure test system. Measure current draw of new pump. Check tire inflation and condition. (also checked transmission fluid level and condition- it was already on the lift and looks like it hasn't been touched in years). Cleared codes and road tested vehicle while monitoring inverter and MG temps at highway speeds. Can't accomplish that in 10 minutes.

If 2 clamps and 3 screws for a new pump then bleed is good enough for you, then I guess we have different opinions as to what a high "quality" repair is.

 

Except that in this case the video is not 20 minutes. The job is 20 minutes (or less).

With enough P0A93 experiences why would you do all them other steps?

 

You did this job like a robot lol no offense. Like you printed out the steps the robots at the dealership do when code is present and follow them step by step.

It's "the good red triangle repair"....You get red triangle and code and you scan hoping it doesn't say "bad hybrid battery"..

If it says: "P0A93, Inverter Cooling System Performance" then it's the pump.

You just pull it off and put it on...Zero coolant spills (maybe a drop?)...zero needs to be added to reservoir...Zero bleeding needs to occur.

 

That's what I was thinking. $30 part and 20 minutes and there's a 99.9% chance you're done.

Its like the P0420 codes.

Step 1 - replace the O2 sensors.
Step 2 - clear codes
Step 3 - wait and see what happens.

Both these are no-brainer moves.
