Check the power to the valve if there is power to it you valve is stuffed. you can also take valve of and put a insulated screw driver in the middle to see if there is any magnetic fource pulling it to the side. .. the solenoid valve is for a reversal valve ?

2-3 shift solenoid circuit


P0758 Chevrolet P0758 Chevrolet - 2-3 Shift Solenoid Circuit Electrical
Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty 2-3 Shift Solenoid Valve
- 2-3 Shift Solenoid Valve harness or connectors
- 2-3 Shift Solenoid Valve circuit is open or shorted
What does this mean? When is the code detected?
When the Powertrain Control Module (PCM) detects a continuous open, short to ground or short to power in the 2-3 Shift Solenoid (SS) valve circuit, then DTC P0758 sets.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission will not shift gears
P0758 Chevrolet Description
The 2-3 Shift Solenoid (SS) valve controls the fluid flow acting on the 2-3 shift valves. The 2-3 SS valve is a normally-open exhaust valve that is used with the 1-2 SS valve in order to allow four different shifting combinations. The solenoid attaches to the control valve body within the transmission. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path.

Quest code p1136


P1136 NISSAN - Intake Valve Timing Control Solenoid Valve Circuit Bank 2
Possible causes- Intake valve timing control solenoid valve bank 2 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 2 circuit connectors
- Intake valve timing control solenoid valve bank 2 Tech notes Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.

Po401 ive cleaned the egr & replaced the egr but i keep getting this code??


depending on your model, there may be a solenoid valve that turns the vacuum to the egr valve on. If the solenoid fails, the egr valve will not open. Follow the vacuum line on the egr valve--does it go to a solenoid valve? If yes, apply 12 volts directly to the solenoid blades to see if it clicks open. If it doesn't click, replace the solenoid.

What is po411 and po445 for 2006 vw jetta/


P0411- Means Secondary Air Injection System Incorrect Flow Detected!
Possible causes - Vacuum hoses damaged.
- Air Pump inoperative.
- Air bypass solenoid circuit open.
- Air bypass solenoid leaking/blocked or stuck open/closed.
- Air diverter valve leaking/blocked or stuck open/closed.
- Air air hoses r Possible solution - Visually inspect vacuum lines for disconnects in the AIR systems and visually inspect for proper vacuum line routing. Repair if necessary.
- Disconnect the air pump hose at the solenoid valve, start the engine and see if there is air being pumped P0445- Means Evaporative Emission Control System Purge Control Valve Circuit Shorted! Possible causes - Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty
P0445 Description The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. When is the code detected? - An excessively high voltage signal is sent to ECM through the valve

Water runs to the solenoid, but doesntt pass through it... Do I need a new solenoid?


Check to see if you are getting 24 volts to the solenoid valve, if you are but the solenoid valve does not click open then the valve is most likely bad. Another thing you can do is apply 24 volts directly to the solenoid valve from the transformer if it does not open then the vlave is bad.
