2013 Dodge Dart Rallye 1.4L Multiair Turbo - 111,000 miles
Clutch and flywheel changed at 105,000 miles

I noticed right after my clutch and flywheel were replaced that when I was in 5th or 6th gear the engine would stutter slightly and be a little choppy on acceleration, but only in the higher speeds/gears. Probably was coincidental but I wanted to mention when I noticed the issues. Like an idiot, I ignored it as I didn't feel it very often.

Fast forward to last week I'm on the highway going about 80 MPH in 6th gear and I felt, didn't hear, a thump and then the car slowly started losing speed despite the RPMs being 3-5000. I was able to maintain about 40 MPH at that RPM all the way home. At a dead stop it will pick up speed but extremely slowly and, again, at high RPMs. I popped the hood and noticed the coolant reserve was empty so I thought maybe a blown head gasket but I never had an issue with overheating and when I topped off the reserve it never lost coolant again.

Now, like most of us with a Dart, I've had issues with burning oil coming through the air vents but never had it repaired as Dodge told me they didn't know what would cause that. I started taking the engine apart and noticed a ton of oil all over the valve cover and surrounding parts as well as on the spark plugs. Now I'm thinking maybe I just need to replace the spark plugs, valve gasket cover, coil over plugs, and air oil seperater and also the waste gate hose I broke :(

However, my question is....even though the oil being on the spark and valve cover is an issue, could that possibly be the reason I lost acceleration power?

Was the CEL flashing? Have you scanned for codes? Are you aware that the 1.4 has a timing belt that needs to be replaced at around 100k miles?

The check engine light did come on but the reader I have at home stated "no codes stored in module" which I assume is because my reader is junk. I had no idea about the timing belt thing I'm learning all of this from YouTube University.

I will say though that the CEL never flashed it just came on and stayed on but I was having that issue due to a P0420 code so not sure that it added more codes to it or not as I couldn't tell with my personal reader. The engine doesn't have any weird noises or rough idling. It seems and sounds perfectly fine until I go to accelerate and then yeah its 5,000 RPMS trying to bring the car up to speed. I will buy another reader tonight and come back here.

So here are the codes:

P2262 - Turbo boost pressure not detected
P0420 - Cat Converter below threshold
P0137 - Oxygen Sensor Circuit Low Voltage
P0302 - Cylinder #2 Misfire

Thoughts? Is it possible my turbo blew?

Check wiring for the O2 sensors and if that's good, replace the O2 sensors. Do not use Bosch O2 sensors, these engines only like NTK. Figure out why you have a misfire on cylinder 2. You won't have boost if you have codes and are in limp in mode.

Ok so I made the following repairs:
  • Changed spark plugs / coils / tube seals
  • Changed valve cover gasket
  • Replaced air/oil separator / ring
  • Replaced wastegaste hose
  • Adjusted the wastegate to 6mm based on some readings I was doing on this site

It idles smoothly and runs seemingly fine in the lower 1-3 gears but I’m back to still having next to no acceleration power above 3rd gear and really can’t maintain anything above 45 MPH.

I have the following code:

P2262 - Turbo Boost Pressure not detected

Any thoughts on what to replace next? The wastegate? The wastegate solenoid? The entire turbo?

28 - DTC-Based Diagnostics / MODULE, Powertrain Control (PCM) / Diagnosis and Testing
Rectangle Slope Font Line Parallel

P2262-00-TURBOCHARGER BOOST PRESSURE NOT DETECTED - MECHANICAL

Theory of Operation

When the accelerator is closed suddenly, excessive boost pressure can build up between the Turbocharger and the Throttle Body which can cause damage to the Turbocharger. This can occur because the compressed air created by the Turbocharger has no place to go. This results in compressor surge. The Powertrain Control Module (PCM) detects this pressure increase via input from the Boost Pressure Sensor. The Boost Pressure Sensor operates as a typical three wire sensor. The PCM provides a 5-volt supply and sensor return circuit to the Boost Pressure Sensor and receives a feedback voltage on the signal circuit. The Turbocharger Surge Valve is responsible for venting the boost pressure between the Turbocharger and Throttle Body during sudden deceleration. The Turbocharger Surge Valve is normally spring loaded closed. When the PCM receives an input signal from the Boost Pressure Sensor that the pressure is above a calibrated amount, the PCM grounds the Turbocharger Surge Valve Control circuit which electrically opens the valve and routes the excess pressure between the Turbocharger and the Throttle Body back to the inlet of the Turbocharger, relieving the pressure and preventing compressor surge.

When Monitored and Set Conditions

When Monitored: This diagnostic runs continuously when the following conditions are met:

•With the engine running.
•When the Wastegate Valve is commanded closed or is open at a value less than 100%.

Set Conditions:

•The difference between the Powertrain Control Module (PCM) (modeled position minus the actual position) is greater than 30 kPa (4.35 PSI).

Default Actions:

•The MIL light will illuminate.

Possible Causes

RESTRICTED AIR FILTER
BOOST SYSTEM PRESSURE HOSES RESTRICTED OR LEAKING
LARGE INTAKE SYSTEM LEAK OR RESTRICTION
INTERCOOLER LEAK
EXHAUST SYSTEM RESTRICTION
WASTEGATE SOLENOID
WASTEGATE VALVE STICKING OPEN
TURBOCHARGER (SEIZED TURBINE)

Always perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE before proceeding. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

1.CHECK FOR CHECK FOR AN ACTIVE DTC

1. Turn the ignition on.

2. With the scan tool, read DTCs and record on the repair order.

3. With the scan tool, erase DTCs in the Powertrain Control Module.

4. Test drive the vehicle.

5. With the scan tool, read DTCs .

Is the DTC active or pending?

Yes

•Go To 2

No

•Perform the INTERMITTENT DTC Diagnostic Procedure. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).


2.CHECK THE AIR FILTER

1. Turn the ignition off.

2. Remove and inspect the Air Filter and housing inlet for snow, soiling or excessive dirt and debris which may cause air flow restriction.

Were any of these problems found?

Yes

•Replace the Air Filter or remove the obstruction.
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Go To 3


3.CHECK FOR INTAKE SYSTEM LEAKS OR RESTRICTIONS

NOTE: Damaged, restricted or poorly connected Intake System and Turbocharger System related tubes can cause this DTC to set.

1. Inspect all air intake, crankcase vent and Turbocharger related hoses/tubes and clamps for leaks or damage.

2. Inspect all boost pressure system hoses for leaks or restrictions.

3. Inspect the Intercooler Assembly for signs of a leak.

Were any problems found?

Yes

•Repair or replace as necessary.
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Go To 4


4.CHECK FOR EXHAUST SYSTEM RESTRICTIONS

1. Inspect the complete exhaust system for damaged, bent or clogged pipes that can cause exhaust system restrictions and excessive back pressure.

Were any problems found?

Yes

•Repair or replace as necessary.
•Perform the POWERTRAIN VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Go To 5


5.WASTEGATE AND SOLENOID INSPECTION

1. Inspect the Wastegate Solenoid, linkage and the Wastegate for proper operation. Refer to the appropriate Service Information.

2. Inspect and test each of the Wastegate Solenoid vacuum/pressure hoses between the engine, the Wastegate Solenoid and the Wastegate Valve.

3. Inspect and test each of the Wastegate Solenoid electrical circuits between the solenoid connector and PCM C1 harness connector.

NOTE: Test each electrical circuit for high resistance, a short to ground and a short to voltage.

Were any problems found?

Yes

•Repair as necessary.
•Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

No

•Repair or replace the Turbocharger in accordance with the Service Information.(Refer to 09 - Engine/Turbocharger System/TURBOCHARGER/Removal) .
•Perform the PCM VERIFICATION TEST. (Refer to 28 - DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure).

Okay so I have another question, and thank you for the responses alpinegreenneon, I am about to swap my turbo for another one and noticed this as I was taking heat shield off and was wondering:

1: what is it?
2: could it be the cause of my “no boost pressure detected” code?

It’s the larger pipe running down to the driver side of the vehicle. The photo with the hose disconnected is from the bottom driver side
Thanks!!

That is a major boost leak.

I can't tell if anything is broken in the picture, but it should clip into place. If not, you may need a new hose.

Just an update. The issue the entire time was that intercooler hose clip broke and fell off and I'm an idiot for not noticing that in the first place. That's what I get for doing most of the diagnostics at night. All issues cleared with the exception of the pesky P0420 code but I bought NTK O2 sensors per alpinegreen's advice so hopefully it clears. The misfire was cleared simply by changing the spark plugs. Thanks to the two of you for helping me out with this one. Now I can sell this junk!
