![]() The pulses tell technicians much more than just checking for battery voltage at the cylinder 8 injector itself. Noid lights are used to check the voltage pulse that operates the fuel injector. This is especially true if the issue is intermittent, as these can be pesky to track down without the proper tools. #FORD ENGINE CODES 7E8 PROFESSIONAL#Scan tools with professional features such as live data stream, graphing functions, and the ability to view data over time will be important for diagnosing P0208. In some scenarios, cleaning the fuel system may allow the fuel injector to operate properly without needing to be replaced. These particles can be made up of dirt, varnish, and contamination inside the gasoline. What repairs can fix the P0208 code?Īdditional comments for consideration regarding the P0208 codeĪs vehicles age, particles can build up in the fuel system. Symptoms such as these can make the vehicle unsafe to drive until it is repaired. When the vehicle runs poorly or has drivability issues, care should be taken and a qualified technician should be contacted as soon as possible. A fuel injector is the most common cause, but the system must be thoroughly tested before it is replaced. Tests the ECM to manufacturer specifications, if neededĬommon mistakes when diagnosing the P0208 codeĪny time a step is skipped or not completed in order, it allows an opportunity for diagnosing the wrong component. Installs a noid light into the wiring for the cylinder 8 fuel injector to check for the proper voltage pulse width Uses the scan tool to check voltage and resistance of the cylinder 8 fuel injector circuit as seen by the ECU (a multimeter will be used to check for voltage at the injector itself) Performs a visual inspection for any damage such as broken or loose wires and connections #FORD ENGINE CODES 7E8 CODE#Installs a scan tool into the diagnostic link connector (DLC) port of the car and scans for any codes stored in the ECM (each code will have freeze frame data which tells technicians what conditions the code was set under)Ĭlears all codes and performs a road test to verify the malfunction (if the vehicle can be driven) How does a mechanic diagnose the P0208 code? This code is similar to codes P0200 - P0207, and P0209 - P0212, which all indicate fuel injector circuit issues.Ĭheck Engine Light is triggered by the ECM and observed on the dashboard after the fault is detectedįailsafe mode (precaution to prevent damage to the vehicle) is enacted by the ECMįailsafe mode remains in effect until the circuit has performance that is within range or the fault is repaired P0208 is set when the Engine Control Module (ECM) detects voltage or resistance that is out of range in the cylinder 8 fuel injector circuit.
