The fuel injector driver/controller is typically integrated into the PCM If all fuel injectors and system circuitry are working fine, then you can suspect a defective controller, or controller programming error. Replace connectors and wirings as necessary.

If no abnormalities are found in the fuel injector operation, then proceed to the next step.Īfter testing the fuel injectors, disconnect all controller from the injector driver circuit, and then use the DVOM to test system circuits. Any proven defective fuel injectors must be replaced. After connecting the oscilloscope test leads, note any inconsistencies in the wave (voltage) pattern. Refer to your 2014 Jaguar XF information for diagnostic flow charts, connector pin-out charts, connector face views, and the recommended testing procedures/specifications for your 2014 Jaguar XF in question. If the system connectors and wirings look good, proceed on testing each individual fuel injector by testing them using the oscilloscope.
#Fuel injector oscilloscope pattern Patch
Trying to patch a fuel injector wiring harness can cause the PCM to receive a skewered fuel injector driver confirmation signal, which will lead to additional codes. You need to replace damaged components, especially the burnt ones. Conduct a visual inspection of all related connectors and wirings.

If the code fails to reset within a reasonable time, you may need for the condition to worsen before you can accurately get an accurate diagnosis. When the PCM enters readiness mode without the code being reset: After writing down all pertinent information, clear the codes and then take your 2014 Jaguar XF for a test drive to see if the code resets, or if the PCM enters readiness mode. You need to write down this information, just in case the problem proves to be intermittent. Start the diagnosis by connecting the scanner to your 2014 Jaguar XF diagnostic port, get all stored codes and other related freeze-frame data. Without the oscilloscope, it will be impossible to diagnose this code, as you will be unable to monitor the injector function. Scanners like Snap-On Modis comes with a built-in DVOM and oscilloscope will work well. To diagnose this code more accurately, make sure you have a diagnostic scanner, DVOM (digital volt/ohmmeter), an oscilloscope, and a source of 2014 Jaguar XF diagnostic information. Open or shorted connector or wiring in the bank 1 injector driver circuit If the PCM sees a fuel injector confirmation signal outside of the expected parameters, then Error Code P062D will be stored, and simultaneously activate the Check Engine light. This allows the PCM to detect problem way before it becomes a drivability issue. This action happens in each cylinder in sequential repetition.Īside from controller the fuel injection system, the PCM also monitors fuel injector circuit feedback resistance for signs of malfunction. Since there is a constant supply of battery voltage on the circuit (when the ignition is on), this activates a precise spray of fuel from the pressurized fuel injector. The fuel injector driver plays an important part in the PCM or EFI (electronic fuel injection) controller (if applicable).īy applying a ground pulse to the circuit at exactly the right time, the PCM controls the injector timing and pulse width. Bank 1 pertains to the bank of the engine that contains the number one cylinder. Specifications on the definition, troubleshooting, and repairs, of course, vary from one make and model to another.Įrror Code P062D means the PCM (powertrain control module, also known as ECM or engine control module in other 2014 Jaguar XF makes) has determined a performance problem with the fuel injector driver circuit for engine Bank 1. This typically shows up in cars from Ford, Honda, Kia, Land Rover, Toyota, Volkswagen, etc. This is a generic trouble code, meaning it applies to all cars equipped with the OBD-II system. Error Code P062D is defined as Fuel Injector Driver Circuit Performance Bank 1.
