Guide To P0207 OBD Error Code Solutions

<<See All OBD Codes

An increase in the fuel consumption and the engine performance along with occasional engine stalling and with improper throttle response and acceleration may be an indication of problem with the fuel pressure system hampering the engine’s performance, thus indicating OBD Code P0207.

This code indicates problems with the fuel injector circuit of the cylinder 7 of the engine, thus affecting the performance and fuel delivery system altogether.

P0207 is a common OBD-II diagnostic trouble code that is set by the Powertrain Control Module when it detects any out of range performance by the Cylinder 7 Fuel Injector. This code may lead to engine misfires as well as rich or lean exhaust conditions, thus affecting the air to fuel ratios and the engine performance and fuel consumptions.

Any noticeable change in voltage of resistance to the injector circuit will set this code and will lead the engine to function in failsafe mode till this error is resolved.

What causes the problem of Cylinder 7 Injector Circuit Malfunction?

• Fuel pump failure or leakage
• Fuel line restricted
• Decreased fuel efficiency
• Faulty fuel pressure sensor
• Fuel pump driver module faulty
• Damaged fuel pump
• Cylinder 7 fuel injector faulty
• Injector circuit problems
• Damaged wiring and connections to the sensor and the circuit
• Restricted Fuel pump supply line

1. Powertrain Control Module - There can be some issues with the Powertrain Control Module due to which you may see P0207 code appearing over and over again. Visit us to buy best quality PCM components and replace them now!
2. Fuel Injector - A lot of issues can arise do to defective Fuel Injector and ca lead to flashing of OBD code P0207 error. Replace faulty injector now!
3. Fuel Pressure Regulator - Faulty Fuel pressure regulator can be the reason why P0207 code getting stored in the PCM. Visit us to buy new fuel pressure regulator today!
4. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, so why not have a look?
5. Fuel Tank Pressure Sensor - OBD code P0207 can also appear due to faulty FPS. Replace it now!

Some of the most common symptoms that indicate towards OBD Code P0207 error are as follows:

Common Symptoms

• Check Engine Light illumination
• Loss of engine power and acceleration
• Loss of throttle response
• Engine misfiring and stalling
• Wiring and connection issues in relation to sensor and circuit
• Engine misfiring and stalling
• Vehicle not running properly

• Replace the following components to resolve OBD code P0207 error.
• Fuel filter replacement
• Cylinder 7 Fuel Injector replacement
• Repair for fluid leakages
• Replacement of damaged fuel lines
• Fuel pump replacement
• Replacement of a faulty fuel pressure sensor

A qualified mechanic begins by using an OBD-II scan tool to read any codes present in the PCM.

• After the code is identified, freeze frame the data and cleared so that the car can be taken for test drive.
• Perform a road test of the vehicle with the similar conditions as that under the freeze frame data to see if the code reappears.
• Check for any open, short, corroded or damaged wirings and connections in association with the sensor and the circuit and repair or replace the faulty wirings immediately.
• If the Check Engine Light comes on, visually inspect the fuel tank, fuel lines, and fuel filter for any faults and damaged that can be repaired or replaced completely.
• Take the manual fuel pressure readings at the fuel rail and compare it to manufacturer’s specifications. Use a scan tool to compare manual readings to what the ECM sees.
• Lastly, the fuel pump is tested and replaced if found faulty. Examine the fuel injector properly for any damages or leaks and replace or repair as necessary. Use the nod light for pulse check and do a sound test to check the proper functioning of the injector.
• Check for PCM (Powertrain Control Module) faults. Although rare in nature, these faults can cause wrong error being stored in the PCM and also hampers the vehicle’s performance by affecting the exhaust system, intake system, fuel delivery system, etc.

Common Mistakes When Diagnosing The P0207 Code

Always take help of a qualified technician with experience to counter the OBD code errors. Use professional factory grade scanning and diagnostic tools to diagnose this problem.

• Missing the diagnosis steps leading to misdiagnosis and error to return
• Though the most common cause is a injector circuit malfunction, it will not be a necessary problem for all vehicles. Thus, proper inspection needs to be done
• It is important to follow the steps so unnecessary repairs are not performed wasting time and money. Never forget to check for faulty or damaged wiring and connections as they can be the reason for the OBD error code and can be a cheap solution to the problem.
