P2708 Dkw F1 Diagnostic Trouble Code
P2708 Dkw F1 code definition:
P2708 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Dkw F1.
P2708 Dkw F1 is described as Intake Air Temperature (IAT) Circuit Malfunction. It's actually a general trouble code for a problem on IAT electrical circuit sensor, as it sends incorrect voltage input signals to the PCM. The PCM then uses this data to provide the right strategies for the fuel delivery and ignition timing of the engine.
Symptoms
Symptoms of a P2708 Dkw F1 diagnostic trouble code may include:
- If the DPF is not cleared the ECU will revert to the "Limp Home Mode" until the situation is corrected
- Corroded or damaged connector
- Reduction in engine performance, especially at low RPM levels
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
|
Possible Causes :
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.
- Faulty IMRC actuator/sensor
- Fuel with a large percentage of sulfur will clog the DPF quickly

Common Misdiagnoses
- Vehicle Speed Output Circuit Problem
- Cruise Control Servo Indicates Low Problem
- A/C System High Pressure High Temperature Problem
- PCM Stack Overrun Problem
- Transmission Control Module Reprogrammable Memory Problem
Repair Processes :
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
Look for damage to the tank indicating impact that may have damaged the fuel pump or sender.
Process Tips
Diagnostic trouble code P2708 Dkw F1 is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before P2708 Dkw F1.
Fortunately, P2708 Dkw F1 is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
