Power seat EGR

P0406 Chrysler - Exhaust Gas Recirculation Position Sensor Circuit High
Possible Causes:
- Faulty EGR volume control solenoid valve
- Carbon built up on EGR valve
- EGR volume control solenoid valve harness is open or shorted
- EGR volume control solenoid valve circuit poor electrical connection
- Faulty EGR temperature sensor and circuit

Did you replace the EGR valve, or the volume control solenoid valve?

you are right posible bad egr valve or you have carbon bild in the egr system and when came loose block the seat at the egr valve seat instal new egr valve with speciar gasket with screen an posible you save a lot

A code of p1400 means that there is an EGR fault in the egr system.These systems are basic and contain most of the same parts.These parts are as follows An EGR valve,Egr valve gasket and an ,Egr valve to manifold tube.I would take a look at the gaskets for the manifold tubes and the EGR valve.I cant tell you where its at without knowing the year ,model,and engine size.But with the information given thats the best I can do for you but this gives you some idea as to where to start.

You can remove the egr and see if it has been sealing,and if it still moves.

Review the correct year for Error Code 32:
32 (1984 only) power loss/limited lamp or circuit
OR
32 EGR gases not working (1988) - check vacuum, valve
OR
32 (1990-92) computer didn’t see change in air/’fuel ratio when EGR activated - check valve, vacuum lines, and EGR electrical

Hope helped (remember rated this help).

well the egr could be stuck open acting like a vacum leak,,,and causing the car to stall,,,you need a new egr,,,,check the wires and if any vacum hoses that go to it,to make sure they are good and connected first,if so replace the egr,,,,it could be false dtc for MAF sensor,,,

egr code can mean egr valve or egr controller you might also have carbon buildup in the engine causing the code

Problem Description: Code 32 means that the EGR diagnostic switch was not detected closed under the following conditions:

• Coolant temperature greater than 80 C (176 F).
  
• EGR duty cycle commanded by the ECM is greater than 50%.
  
• Manifold pressure less than 25 kPa, (7" vacuum).
  
• All conditions above must be met for about 8 seconds.

Diagnostic Aids: A Scantool can be used to check the diagnostic switch circuit. The Scantool should display "on" when vacuum is applied to the diagnostic switch. The switch should also be indicated as being closed whenever the ECM is commanding an EGR duty cycle of greater than 50%. EGR duty cycle can also be monitored by a Scantool.



"Scan" Diagnostics: Before using this test, check for ported vacuum to EGR solenoid, also check hoses for leaks or restrictions. There should be at least 7"hg vacuum at 2000 rpm.
Disconnect EGR solenoid vacuum harness. Rotate harness and reinstall only the EGR valve side. Ignition on, engine stopped. Install a hand held vacuum pump with gauge to mainfold side of EGR solenoid. Apply vacuum and observe EGR valve, the valve should not move.
Valve does not move Valve moves

the 12 code is the start for the codes to be read code 32 is a map sensor code but does not mean that , i have a 91 sonoma and same codes turns out it wes my intake gaskets

You should have your battery checked, it may be getting old and doesn;t have as much cold cranking power, I don;t think code 32 has anything to do with the slow cranking when cold.


Trouble Code 32 indicates that the Exhaust Gas Recirculation (EGR) valve diaphragm is not where the ECM expects it to be. The ECM controls the diaphragm with a Pulse-Width Modulated (PWM) waveform. The EGR has a vacuum bleed solenoid that adjusts the vacuum applied to the EGR valve based on this pulse width. If there is sufficient vacuum at the EGR valve, a switch closes to send a signal back to the ECM. The absence of this signal is the bases for code 32.
The conditions for setting this code are:

• no vacuum to EGR (switch open), and
• Code 33 or 34 (MAF error) is not present, and
• engine running and LV8 is less than 100, and
• coolant temperature is > 118 deg F (48 deg C), and
• the EGR solenoid duty cycle is < 65%, and
• the above conditions are met for more than 25 seconds

Typical causes for this code include:
1) Faulty EGR valve-to-ECM connection
2) Plugged EGR passages and/or sticking EGR valve
3) Defective EGR valve
4) Defective ECM
