Location of wastegate solenoid


If you do not know the location of the wastegate solenoid, how could you have properly tested it? Then, if you have not properly tested it, how could you possibly know that it actually needs to be replaced? - (just asking to provoke thought)

Hint: If you are getting a fault code that says "turbocharger wastegate solenoid control circuit" (like maybe a P0243), it would be wise to check the circuit before just throwing parts at the car...the solenoid might not be the problem.

With all that said, the answer to your question is that it is on the other end of the vacuum hose that goes to the waste gate valve - top rear of the engine above the left valve cover.

P1250


The location of WHAT???

Diagnostic Test Code (DTC) P1250 is a manufacturer - specific code which has a general description of "Pressure Regulator Control (PRC) Solenoid Circuit Malfunction".

The PCM monitors input voltage at Pin number 44 when the ignition is turned on. DTC P1250 sets when less than .44 volts are present. The possible causes are:
> PRC Valve malfunction (open or shorted internally)
> Open or short circuit between the PRC valve and the PCM (control circuit)
> Open or short circuit in the solenoid ignition voltage supply circuit
> Failed PRC valve (stuck open)
> Malfunctioning PCM

zjlimited_344.gif

Measure the voltage between the (K139) Wastegate Solenoid driver circuit at the Wastegate Solenoid connector and battery negative.

Is the voltage less than 1 volt?
Yes
Go To 7

No

Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL).


7. (K139) WASTEGATE SOLENOID DRIVER CIRCUIT SHORTED TO ANOTHER CIRCUIT

zjlimited_345.gif

Measure the resistance between the (K139) Wastegate Solenoid driver circuit in the ECM harness connector and all other circuits in the ECM harness connectors.

Is the resistance less than 10 Ohms?
Yes
Repair the (K139) Wastegate solenoid circuit shorted to another circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1 (DIESEL). (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)


No
Go To8


8. WASTEGATE SOLENOID

zjlimited_346.gif
Reconnect the ECM harness connector.
Reconnect the disconnected Wastegate Solenoid harness connector.
Turn the Ignition on, engine not running.
Disconnect the Wastegate Solenoid harness connector.
Connect an incandescent test light across the supply and driver pins at the Wastegate Solenoid harness connector.

I got a 1994 dodge intrepid and I have 2 codes up on it and i dont know what they are. Code 35 and 45?


Fault Code 35
Description: Radiator fan relay circuit is open or shorted
Power loss light: Off
Limp-in mode: None

Possible Causes:
Bad connection or wiring - Check the wiring and connections between the logic module and the relay. Clean and regrease any corroded connectors with dielectric grease and repair any shorts.

Bad relay - Disconnect the relay and apply 12V across the coil terminals (between the white wire and either of the other two terminals on the small connector). You should hear a click for either of the two termials and the connection between the grey wire and the other two terminals of the large connector should be shorted.

Diagnostic Method
Trigger Parameters
- Near 0V or near 12V not detected when the relay is turned on or off, respectively
Results If Component Fails
Fault code 35 is stored.


Fault Code 45
Notes: For Turbo models only

Description: Turbo boost limit exceeded
Power loss light: On
Limp-in mode: None

Possible Causes
Vaccum leak - Check all vaccum lines between the wastegate actuator, manifold, and wastegate solenoid. Also check the line to the MAP sensor. Repair or replace any bad lines.

Wastegate solenoid failure - The wastegate solenoid is located in the right, front fender next to one to three other solenoids. See the Understanding Solenoids page.

Bad connection or wiring - Check the wiring and connections between the logic modle (or SMEC) and the wastegate solenoid. Clean and regrease any corroded connectors with dielectric grease and repair any shorts. This condition may be accompanied by a code 36.

Wastegate actuator spring failure - Try to slide the wastegate to wastegate actuator push rod into the actuator. It should not move. Try to pull it out. If it pulls out with little effort (even if it springs back in), replace the actuator.

Jammed wastegate - Disconnect the wastegate actuator pushrod and swing the wastegate arm on top of the turbo. It should have about a 50 degree swing. Make sure the lever and push rod are clear of any obsticles that may cause them to jam (the heat shield below the fuel rail is a major culprit).

Diagnostic Method
Trigger Parameters
- MAP sensor output voltage has exceeded overboost cut-off point

zjlimited_942.jpg

Following years are probably the same as 1987, but I don't have any hard data to back that up. Some have said that 4.74V was the max for Turbo I engines of later years. Some information indicates that the Turbo II with an automatic had a cut-off of 4.96V, but I don't know of any Turbo II vehicle that had an automatic transmission.

Results If Component Fails
A fault code 45 is stored, the power loss light is turned on, and the fuel injectors are shut off. Once the boost has fallen to 3 psi to 5 psi, the fuel injectors are turned back on and the power loss light is turned off. The overboost cut-off point for a particular vehicle depends on the year, engine, and transmission.

Check engine codes for a 1997 stratus the codes coming up are 12 31 and 55


12 Recently disconnected the battery (always stored)
55 End test.

CODE 31... depending on the model, code 31 can refer to two different systems. Please choose from one of the above links for specific information on each system.

Wastegate Solenoid Circuit Error
The ECM regulates turbocharger boost by opening and closing the "wastegate" as necessary. (The wastegate is a vacuum operated bypass valve that limits the ability of the turbo to provide boost.) The Wastegate Solenoid regulates the vacuum supply to the wastegate for proper operation.

Fault Code Description
  • 31 - Wastegate Solenoid circuit error
Symptoms
  • Lack of power or engine "ping" due to overboost by the turbocharger
Common Problems
  • The wastegate solenoid would be the most common cause for code 31 to set
  • Code 31 does not indicate a problem with the turbocharger or wastegate


Gear Position Switch (PRNDL) Error The Gear Position switch tells the ECM which position the shifter is in. The ECM will use this information to inhibit starter operation, change the transmission shift pattern as necessary, and provide the information for the electronic shift indicator display on the dash.

Fault Code Description
  • 31 - Gear Position switch (PRNDL) error
Symptoms
  • Engine may not crank over in Park or Neutral
  • Electronic shift indicator may flash
Common Problems
A maladjusted or failed Gear Position switch would be the most common cause for a code 31


Hope helps with this (remember rated this post).
