Error Code P020E: What It Means & What To Do?

<<See All OBD Codes

Are you confronting issues like poor acceleration, engine surge, possible spark knocks or red-hot catalytic converter? If yes then please don’t ignore them as these are the prime symptoms of OBD trouble code P020E. OBD-II Code Decreased engine performance is defined as a Cylinder 5 Injection Timing. This code is set when PCM detects a malfunction in the injection timing circuit for a particular cylinder of the engine. In this case, the cylinder in question is cylinder five.

P020E Code is stored in vehicles equipped with diesel engines. The Powertrain Control Module (PCM) can detect when unintended fuel injection occurs by monitoring fuel rail pressure and engine speed. In this situation your engine will not start. There will be exhaust smoke during cranking and no fuel rail pressure will be developed during cranking. OBD scanner will store code P020E and indicates the problem which occurring.

What causes this problem Cylinder 5 Injection Timing?

• Faulty Crankshaft and camshaft position sensor
• Frayed wiring and connectors
• Lean air mixture
• Rugged engine due to misfiring plugs
• Fuel injector 5 harness is open or shorted

1. Fuel Injector - Fuel injectors are the components that are responsible for the final stage of fuel delivery in fuel injection systems. Ensure its efficient functionality to avoid any trouble code.
2. Fuel Injector Solenoid - Solenoid valve injector injects into the cylinder the amount of fuel required for economical combustion. Make sure it is working properly else can lead to various problems.
3. Powertrain Control Module - May be your timing belt is good and there are some issues with the powertrain control module. Then don’t waste time and purchase best powertrain control module with us.
4. Camshaft Sensor - The camshaft position sensor gathers information about the vehicle's camshaft speed and sends it to the vehicle's engine control module (ECM). So, replace or repair it if found faulty.
5. Crankshaft Sensor - Crankshaft position sensor usually registers the rate at which the crankshaft spins. The ECU then makes use of this information to regulate ignition and fuel injection. Always have a look on this, if found faulty can lead to this code.
6. Diagnostic Tool - Always use high grade diagnostic tools to diagnose any error in your vehicle and we have a wide range of best quality tools available on our web. Explore now!

Below are the common symptoms for the code P020E. If you experience below mentioned symptoms please bring your vehicle to a reputable repair facility. If neglected it could develop into something much more serious fairly quickly.

• Raised fuel consumption
• Reduced engine performance
• Distinctive smell of fuel
• Engine misfiring
• Illuminated check engine light

The step by step analysis and diagnosis is recommended by a qualified technician using high grade diagnostic tools to check for all the problems and solving them. Follow the below mentioned steps while correcting this code:

• Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1.
• If an oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed.
• 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.

This trouble code is considered generic because it applies to all makes and models of vehicles, although specific repair steps may be different depending on your car model. Keep the below mentioned points in mind while fixing this code but it’s always good to have a qualified technician to look after your vehicle when this error code arises.

• Always use high grade diagnostic tools; here we require a scanner, a digital voltmeter / ohmmeter to diagnose a code P020E.
• Begin with a visual inspection of high-pressure fuel system related components and wiring harnesses.
• Look if there is fuel leakage as well as damage to wiring or connectors.
• Always refer technical service bulletins (TSB) which relate to the vehicle, symptoms, and codes if available.
• Connect the scanner to the vehicle diagnostic port and restore all stored trouble codes and freeze frame data.
• Clear the codes and test-drive the vehicle to see if the code is reset.
• If there is crankshaft sensor or camshaft position sensor codes stored then diagnose and repair those before attempting to diagnose the injector timing code.

Common Mistakes When Diagnosing the P020E Code

We hereby recommend you all to always approach a qualified technician or mechanic to diagnose the code P020E because of intense fuel pressure. Generally, people commit various mistakes while diagnosing this code like

• Replacing the fuel injectors when the problem is with unclean or dirty fuel filter.
• Glow plugs may worn out and not changed or the faulty glow plug relay.
• May have defective fuel supply pump that was not replaced.
• There might be some failure with the Fuel injector.
