Frequently Asked Questions about P2074 Chrysler Code
What does the OBDII code P2074 mean on a Chrysler vehicle?
P2074 indicates a "Manifold Pressure/Throttle Position Correlation - High Flow/Vacuum Leak," meaning there’s a mismatch between the throttle position and the airflow measured by the manifold pressure sensor.
What are the common symptoms of code P2074 in a Chrysler?
Symptoms may include rough idling, reduced engine performance, stalling, poor fuel efficiency, and the Check Engine Light turning on.
What causes the P2074 code to trigger?
Common causes include vacuum leaks, a dirty or faulty throttle body, a malfunctioning manifold absolute pressure (MAP) sensor, or problems with the mass airflow (MAF) sensor.
Can a vacuum leak cause the P2074 code?
Yes, a vacuum leak is a frequent cause of this code as it disrupts the correlation between the throttle position and manifold pressure.
How do I diagnose the P2074 code on my Chrysler?
Start by checking for vacuum leaks, inspecting the throttle body for dirt or damage, testing the MAP and MAF sensors, and verifying wiring connections.
Can a dirty throttle body trigger the P2074 code?
Yes, a dirty throttle body may cause incorrect airflow readings, leading to a mismatch and triggering the code.
Is it safe to drive with a P2074 code active?
While the vehicle may still be drivable, it’s not recommended as it can lead to reduced performance and potentially damage the engine over time.
How can I fix the P2074 code on my Chrysler?
Repairs may include cleaning or replacing the throttle body, fixing vacuum leaks, replacing faulty sensors, or addressing wiring issues.
Will clearing the code without fixing the issue solve the problem?
No, clearing the code without addressing the underlying issue will only temporarily turn off the Check Engine Light, and the code will likely return.
How much does it typically cost to repair code P2074?
Repair costs vary but may range from $50 for a simple sensor cleaning to $500 or more for parts replacement and labor, depending on the root cause.

HELLO, WHAT WOULD CAUSE THE CODE P2074 TO COME ON AND OFF BY IT SELF ONCE OR TWICE A WEEK- THE CAR SEEMS TO RUN GOOD IF THE CODE IS ON OR OFF??? THANKS
-
The first thing you need to check is for vacuum leaks. Inspect the intake manifold for leaks, hose to the brake booster and PCV valve, and any other vacuum hose. If you can't find any leaks, you may have to replace the MAP sensor.
-
HELLO, NO VACUUM LEAKS DETECTED FOR 08 PT CRUISER CODE 2074,
REPLACED THE MAP SENSOR AS RECOMENDED AND I STILL HAVE THE
P2074 CODE POP UP, BUT NOW THE ENGINE BUCKS OR JERKS WHEN THE
CODE COMES ON ,BUT STILL RUNS AS IF NOTHING IS WRONG, WHAT SHOULD I LOOK FOR NOW, THANKS FOR ANY HELP -
Would a bad gasket/seal on a spark plug tube cause the code? when I removed spark plug closest to the battery the spark plug wire and & spark plug were completely coated in oil.
-
What model and year is your Chrysler? It's unlikely that the oil on the plug is the problem, but that is something you should definitely fix. Most of the times the solution to the P2074 code is the map sensor.
-
Can bad fuel injectors cause this problem as well? I have a cylinder three misfire detected so I switched fuel injectors with cylinder 1 and now its cylinder three and two giving me problems but it is running a little bit better. This car has been a nightmare so far. I did replace coil pack and plug and wires. I've also replaced a camshaft posuitiong sensor as that gave me problems too.

2008 Chrysler PT Cruiser. I have replaced the TPS and the MAP. Checked thoroughly for vacuum leakes, hoses, throttle body, etc. o rings on intake manifold and throttle body seem good. Still idling extremely high (30 - 40,000 rpms) upon start and 20,000 under load. In park after being under a load idle revs up and down to an almost stall. Only code is P2074. Help! Is it the ECM?
-
Unfortunately, I never had that problem before, but according to a national database of repairs for your model and year, the Throttle Body and Spark Plugs are the most likely cause of the problem, after the TPS and MAP sensors.
-
I did change the spark plugs recently. I went with Bosch iradium tip per the recommendation of the guy at the auto parts store. I know these aren’t the original type. Unfortunately threw those out. Car ran fine for a while afterwards but maybe these plugs are causing the high idle? I’ll replace again with standard plugs an update if any change. Thanks.
-
UPDATE - FIXED. Decided to remove and inspect the ICV (idle control valve) located on the throttle body itself. Discovered a small piece of wood debris lodged inside preventing the valve from closing. Once I removed the small obstruction no issues! I have no idea how that worked it’s way in there.

I just bought 2005 pt cruiser turbo and the previous owner was told after having it diagnostic done it needed new PCM because check engine light was on . He ordered off eBay installed himself light went out and first week I got the care light was on I checked for codes and P2074 comes up. When I go up small hill and hit gas just a little it don't seems as if it wants to go and car idles rough and the check engine light back on. Air filter was dirty changed it now I'm wondering do I need to change map sensor? Or should I change Mass Air flow Senor or maybe both? Help
-
The MAP sensor is indeed the most likely cause of the problem. If the problem persist you next step is to have the PCM reprogram.

If I had the manifold off, or just unscrewed to get to the radiator hose and started the engine, could doing that trigger the code and the not go away, even after manifold is attached back correctly? In other words, if that could or would cause a 2074 code to pop up I'll it stay until I do the reset thing.?
-
Yes, it's possible. Have you tried clearing the code? how long it takes to comeback?
-
Well I'm in the process to be honest of replacing the fan because mine has the overheating problem. I checked the fuses the relay the thermostat the cap bled the system in five different ways, which I didn't even know was supposed to be done however I just moved to Denver where it's cold and prior lifted Florida where a thermostat was it needed, lol. I should know today if the code comes back on another question is could that cause anything with the overheating issue?

I have a 2004 ram 1500 with error codes 2074, 0300, 0068, and 0113. I've changed the spark plugs, the coils, and the injectors in an attempt to fix the p0300 but this morning the p0068 code appeared after filling up on gas and putting a bit of injector cleaner into the tank, by the time I got home all the rest of the codes started up and I can get it running but it wont stay on for longer then a minute. What would cause all 3 new issues to pop up? Could this be a heasgasket issue? I've replaced the throttle position sensor as well
-
You should check for vacuum leaks near the Mass Air Flow (MAF) Sensor, it's possible that during the spark plugs installation you left something loose. The P0068 and P0113 code are related to the MAF
