Corolla / Matrix 2009-13 :: Change / Clean PCV Valve?
I have an '09 with 138k miles on it, I was wondering where the PCV Valve is on the 10th gen, and how to remove it to either replace or clean it?

I had the PCV valve replaced around 60K, then at the next service they wanted to do it again (not reading the records that they had already done it). Then at 80K they wanted to do it again, I declined. Today it was in for 85K service and they said "the PCV valve is dirty and needs to be replaced." The advisor told me after the initial replacement at 60K the interval is 20-25K miles.

When I did the PCV valve on my wife's car it looked like nothing more than a metal housing with a ball bearing rattling around inside. That left me wondering, why not just clean and reinstall the original valve? Is there a reason why that wouldn't be nearly as good? I realize it's a $10 part but I have to ask the question before I go buy another for my own car.

I have a 2004 toyota Prius with 185k miles on it and recently got the CEL for P1121. I checked both coolants and turns out that the engine coolant was completely out. I immediately filled it up and the CEL went off for a couple days. It has come back and is on constantly, I checked the coolant and the coolant is at the correct level.

I had my a/c recharged in April and it was blowing hot again by July. I brought it back in today and they told me that it is leaking out of the Schrader valve on the low pressure side. They told me that they would have to replace the entire line which would cost a few hundred just in parts. Why can't they just replace the valve. The tried calling auto stores for a special part, but could not find one. How to seal or repair just the leaking Schrader valve and not the entire line?

2004 Prius, 98K miles ... I recently replaced the coolant control valve (received code P1121) and added coolant. Trouble codes were cleared. I am now getting the red triangle intermittently. When I drive the car, after a few minutes, the red triangle comes on. I can shut off the car, and turn it back on, and the red triangle comes back after a few minutes. The car seems to drive normally.

I have read all the posts pertaining to this code, replaced my coolant flow valve, bled all the air out of the coolant system and still am getting the cel with the 1121 code.
I have tried setting multiple coolant flow valve positions, checked all wiring in harness, coolant level is full in rad and reservoir, checked temp sensor at bottom of storage tank, checked pump operation at top of tank to attempt to clear this code to no avail.
Is there a default position the valve is to be in before cold start up?
Is there anything else that can trigger this code? What am I missing?
Prius (2004-09) :: Camshaft Gear And Valve Cover Need To Be Replaced / CEL Came On
Yesterday the check engine light came on in my 2006 Prius. I took it to the dealer, and they said that the camshaft gear and valve cover need to be replaced. Specifically, the diagnostic report says "P0011. Camshaft position A timing over. Advanced or system performance bank 1. Pin point check LED to CUV gear not switching."

We've gotten quite a bit of rain in the LA area over the last couple of days and I noticed today that sometimes when I start/turn-off the car I hear what sounds like a liquid sloshing around behind the dashboard. Reading on the boards it sounds like a clogged A/C drain, but as it happens I just had the Coolant Valve replaced yesterday (after CEL came on with a P1121 diagnostic code) and so I wanted to check in -- could this be at all related to the new valve OR is it likely just a coincidence?

My 2004 Prius with 224k miles is throwing a P0080 code (exhaust valve solenoid stuck high). So, I brought it to the dealer. They just called me saying that the main battery needs to be replaced. My battery graph shows that it's ok and the hybrid functionality works flawlessly.

I have a 2009 Prius and the check engine light came on last week. I decided to take it to a highly recommended auto repair shop instead of the dealer. The error cord was P1121 and they replaced some kind of coolant control valve. When I went to take the car home I noticed the check engine light was still on and they said there was another similar but different coolant valve that needed to be replaced. They replaced the other part and everything seemed fine.

View 3 RepliesPrius (2004-09) :: Intermittent Buzzing Sound From Engine Bay - Bad Coolant Flow Control Valve
For several months now, my 2007 Prius has been making an intermittent buzzing sound from the engine bay. When I first heard it, I thought I had hit the little lines they cut into the road to let you know you've drifted over the center line - the sound is like that, a low-pitched buzzing noise. Today, the check engine light came on as it was making that noise. I put a code reader on the car and got P1121, a bad coolant flow control valve. Wondering if the sound and the faulty control valve are just coincidental or if the valve might make that noise when it fails? And if not the valve, what the sound might be?

I had the red triangle pop up on my Prius. I codes I got P0A93 and P1121 I needed a new control valve and inverter water pump. I installed both the valve and the inverter pump filled it with new coolant and bled both systems.
I went into maintenance mode so I could run the motor and bleed out all the water. My question is the red triangle is still on in my car when I start it up.. Is there some way to clear the red triangle or does it just go away on its own? Not sure what to do.
Prius (2004-09) :: 2008 - Getting P1121 / P1116 - Replaced Coolant Control Valve And Red Triangle?
So I drive a 2008 and a couple months ago I started getting the Check Engine Light. Codes P1121 & P1116. Found out it was most likely related to a faulty Coolant Control Valve or Electric Water Pump. Since the pump was just recently changed I went ahead and got the valve changed.
The light is still coming and going but now when I go on the expressway that red triangle with the exclamation pops on with a little beep. Only pops on for a couple seconds and keeps coming back until I drive a bit slower.
Prius (2004-09) :: Mileage Dropped After Oil Change
I have an 05 Prius that I bought used. It has 59K miles on it. Recently I took it to the dealer for an oil change. They told me it didn't need an oil change, but did need an air filter. Afterwards, the mileage dropped from about 47 around town to about 42. Had the oil changed a week later, and the mileage is now about 40 around town. The dipstick when cold shows a little above the full mark.
