Replaced injector p208 and code doesn't clear.

The P0208 code on your 2012 Mercedes Sprinter is likely a false positive. This code indicates an injector circuit malfunction on cylinder 8, but your Sprinter only has 6 cylinders. The most likely cause of this code is a problem with the wiring harness or connection to the injector. To clear the P0208 code, you can try the following: Inspect the wiring harness for any damage or loose connections. Clean the injector connector with electrical contact cleaner. Reinstall the injector and clear the code with your scan tool. If the code persists after these steps, you may need to replace the injector or wiring harness. The P2453 code is an error in the DPF sensor. This code can be cleared by performing a regeneration of the DPF. You can do this by driving the vehicle at a steady speed of 50-60 mph for 20-30 minutes. If the P2453 code persists after performing a regeneration, you may need to replace the DPF sensor. It is important to note that these are just some general troubleshooting steps. The specific cause of your codes may vary. If you are unable to clear the codes yourself, it is best to take your vehicle to a qualified mechanic for diagnosis.

code p 208E refers to reductant injector 1 bank 1---stuck closed ===causes --reductant injector

this publication list many causes for trouble codes and as there is only cause listed here, it would be logical to replace the faulty unit

Hi there:
P0205 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero. When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.


Potential Symptoms The symptoms for this code will likely be a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.

The causes of a P0205 engine light code could be any of the following:

• Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
• Open in the wiring to the injector
• Short in the wiring to the injector
• Bad PCM

Possible Solutions

1. First, using a DVOM check the resistance of the injector. If it isn't within specs, then replace the injector.
2. Check for voltage at the fuel injector connector. It should have 10 volts or more.
3. Visually check the connector for damage or broken wires.
4. Visually check the injector for damage.
5. If you have access to an injector tester, activate the injector and see if it operates. If the injector operates, then you likely have either an open in the wiring, or a blocked injector. If you do not have access to a tester, swap the injector with another one and see if the code changes. If the code changes, then change the injector.
6. At the PCM, remove the driver wire from the PCM connector and Ground the wire. (Make sure you have the correct wire. If you're not sure, do not attempt) The injector should activate
7. Replace the injector

Hoe this helps.

Nr 3 injector faulty or open circuit to nr 3 injector. You could swap injector to another cylinder, clear the code & see if the code changes to another cylinder (PO201 nr 1, PO202 nr2 etc) then you know the injector is faulty or you could just replace & clear & see how you go. Most likly cause is the injector.

P0303 is cylinder #3 misfire detected. Start by changing the spark plug. If that doesn't clear it then try changing the plug wire. If that doesn't clear it, then you might need to look at the injector.

I would change out all the plugs at the same time, clear the light and see if it comes back. If it does then change all the plug wires, distributor cap and rotor (if it has them).
