P2416 OBD Error Code: Problem & Solutions

<<See All OBD Codes

When this code is set it means that the Engine Control Module (ECM) has detected a problem with the signal output form the wiring harness of the two sensors on the either side of the motor.

It normally has direct implications on the fuel delivery system causing increase in fuel consumption as well as engine stalling and not starting. The first indication of the fault in always the check engine light and immediate loss of power form the engine, thus implying Code P2416 error.

P2416 is a specific code indicating a problem with the bank 1 sensors. The engine control unit (ECU) has detected swapped sensor signals for sensor 2 and 3 for bank 1. This may be indicated by a flashing Check Engine Light and the vehicle’s ECU triggering a failsafe mode.

What causes this problem with the O2 Sensor Signals Swapped Bank 1 Sensor 2/Bank 1 Sensor 3?

• The connectors for bank 1 sensor 2 and bank 1 sensor 3 have been swapped
• Crossed oxygen sensor wiring
• ECU failure
• Open or short in oxygen sensor wiring for bank 1 sensors

1. Engine Control Module – ECM faults are rare but can be a big problem as faulty ECM will cause wrong vehicle operations and can also result in wrong OBD codes getting stored in the system which can also cause misdiagnosis. Thus, replace faulty ECM components now!
2. Electronic Control Unit – The ECU coordinates with the temperature sensor to control the blower fan for keeping the battery temperatures under control. So, replace faulty ECU components now!
3. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else this fault code can turn up.
4. Fuel Injector - Faulty fuel injector, it will cause rough idles and difficulty in starting. Also, it will affect the fuel economy and engine performance. Fuel injector can also crack or break leading to leakages and should be replaced immediately.
5. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
6. Powertrain Control Module – Check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
7. Oxygen Sensor – Inspect for faulty O2 sensor that can affect the engine combustion process and the exhaust emissions. Thus, it is important to understand its importance and replace faulty oxygen sensor now!
8. Manifold Absolute Pressure Sensor - The MAP sensor would fail by getting clogged, contaminated, or sometimes damaged. There can be times when the engine heat would “overcook” the electronics of the MAP sensor and can cause cracks vacuum lines. So it is very important to take proper care of the MAP sensor and in case you need a new one, then Parts Avatar is here at your service.
9. Diagnostic Tool - In order to detect the error, one needs high grade diagnostic tools. Visit us today to grab amazing deals.

Interested in knowing the symptoms to obd code P2416? If yes, then you have arrived at the right place. We at PartsAvatar have listed out few common symptoms associated with this fuel injector problem.

Common Symptoms

• Loss of response from engine and throttle
• Increased fuel consumptions
• Check Engine Light On
• Rough engine idles
• Engine running low on power

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue you need to follow certain steps, and to solve OBD error code P2416, you will need to undergo the following replacements:

• Installing connectors on proper sensors
• Repairing or replacing wiring
• Repairing or replacing ECU

Apart from this, you might need to replace other damaged parts too like Oxygen Sensor, Electrical Connector, Fuel Pressure, PCM, ECM, Wiring Harnesses, Air Fuel Sensor, Digital Volt, Ohmmeter, Battery and more. You can easily find all these parts with us. Not only that you can get these parts shipped to your door free, if your cart value happens to exceed $99.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2416 code to be stored:

• The mechanic will begin by hooking up a scan tool into the car's OBD-II port and confirming P2416 is present.
• If P2416 is confirmed, the freeze frame data will be observed to tell us what conditions the code was set under.
• The code will be cleared and the vehicle taken on a road test by the mechanic to duplicate the code.
• After the code is observed, the mechanic will perform a visual inspection and confirm the connectors are going to the correct sensors.
• If the connectors are in the proper location, the wiring will be both visually inspected for shorts and a continuity test will be performed to ensure the wiring is not open or shorted together.
• If all else fails the mechanic will perform the manufacturer's specific test for the vehicle’s ECU.

Common Mistakes When Diagnosing the P2416 Code

P2416 is an uncommon code that is usually seen from simply plugging the sensor connectors in the other side’s sensor. This code should be diagnosed by the books and care should be taken to make sure the connectors are plugged into the right sides before a more extensive diagnostic is performed.
