P0124 Tvr T440 Diagnostic Trouble Code
P0124 Tvr T440 code definition:
P0124 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Tvr T440.
P0124 Tvr T440 is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3. Other symptoms that may indicate this problem are when the Check Engine Light illuminates and when there is a visible lack of engine power.
Symptoms
Symptoms of a P0124 Tvr T440 diagnostic trouble code may include:
- Faulty or damaged wiring
- 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
- Poor fuel economy
- Reduction in engine performance, especially at low RPM levels
|
Possible Causes :
- Defective ECU strategies or components will prevent proper regeneration
- The Mass Airflow sensor is a hot wire that senses the volume of air entering the intake manifold. The computer uses this information to control fuel mixture.
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

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 :
Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector.
You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data.
Look at the plug wires to make sure they are not burnt or laying on the exhaust.
Process Tips
Diagnostic trouble code P0124 Tvr T440 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 P0124 Tvr T440.
Fortunately, P0124 Tvr T440 is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
