How can I replace transmission control solenoid?


Control solenoid ? explain . Shift solenoid , pressure control solenoid ?
The shift solenoid valves are two identical, normally open, electronic exhaust valves that control upshifts and downshifts in all forward gear ranges. These shift solenoid valves work together in a combination of ON and OFF sequences in order to control the positions of the 1-2, 2-3 and 3-4 shift valve trains. The PCM monitors numerous inputs in order to determine the appropriate solenoid state combination and the transmission gear for the vehicle operating conditions
The pressure control (PC) solenoid valve is a precision electronic pressure regulator that controls transmission line pressure based on current flow through its coil windings. As current flow is increased, the magnetic field which is produced by the coil moves the solenoid's plunger further away from the exhaust port. Opening the exhaust port decreases the output fluid pressure, which is regulated by the PC solenoid valve. This ultimately decreases line pressure. The PCM controls the PC solenoid valve based upon various inputs including throttle position, fluid temperature, MAP sensor, and gear state.
Did you have a DTC - diagnostic trouble code ?

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.

P0977


Shift Solenoid B Control Circuit High

Areas to check:
  • Short in shift solenoid valve No. 2 circuit
  • Shift solenoid valve No. 2
  • ECM

  • Check the shift solenoid valve No. 2 when DTC P0976 and P0977 is output.
  • Check harness and connector between ECM and shift solenoid valve No. 1 or No. 2.
To check the Shift Solenoid Valve No. 2:
  1. Jack up the vehicle.
  2. Remove the oil pan.
  3. Remove the shift solenoid valve No. 1 or No. 2.
CHECK:
  1. Measure the resistance between the solenoid connector terminal and the body ground. Standard: 11 - 15 W at 20°C (68°F)
  2. Connect the battery positive lead to the solenoid connector terminal and the battery negative lead to the solenoid body ground. Standard: Solenoid operation noise is produced. If not, Replace solenoid valve. If the Solenoid operation noise is produced, Check and replace the ECM.

I have a 2002 honda accord, V6 with 42,000 miles,,,yes,,,42,000 miles The check engine light went on, the dealer checked the code "p0780" Replace transmission. Can this be right?


The code you have P0780 is an internal hydraulic problem in the transmission. I did some research on this trouble code and the repair manual Say's to replace the torque converter clutch solenoid valve/shift solenoid valve A, and the A/T clutch pressure control solenoid valves A and B.

In plain English these are the shift solenoids and torque converter solenoids. These solenoids control the fluid flow to the transmission and if they are not working properly then p0780 will set.

The bad news is the repair manual Say's to replace these solenoids and if the problem is still present then replace or overhaul the transmission because the problem is internal.

Most repair shops are not going to take the risk and just replace the solenoids, they will replace or overhaul the transmission.

I have a 2003 a4/b6 1.8 turbo and the engine light is on. The DTC codes says random misfire, misfire on cylinder #2 and #3 also, Oxygen (Lambda) Sensor Regulation: Bank 1: System too Lean : P1111. Any...


If you can supply me with all the codes your vehicle is showing, I can assist you. As far as the P1111 DTC goes I have listed the info below with some possible solutions.

P1111- Intake Valve Timing Control Solenoid Valve Circuit Bank 1

Intake valve timing control solenoid valve is activated by ON/OFF pulse duty (ratio) signals from the ECM. The intake valve timing control solenoid valve changes the oil amount and direction of flow through intake valve timing control unit or stops oil flow. The longer pulse width advances valve angle. The shorter pulse width retards valve angle. When ON and OFF pulse widths become equal, the solenoid valve stops oil pressure flow to fix the intake valve angle at the control position. The code is triggered when an improper voltage is sent to the ECM through intake valve timing control solenoid valve. 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.

Possible Causes:
- Intake valve timing control solenoid valve bank 1 circuit is open or shorted.
- Intake valve timing control solenoid valve bank 1 circuit connectors
- Intake valve timing control solenoid valve bank 1
- Dirty Oil

Possible Solutions:
- Change Oil
- Replace Intake valve timing control solenoid valve
