The P0351 code can have some drivability symptoms that will not make it safe to drive depending on how severe the symptoms are. Mistakes are made when components are replaced without being test or all steps are not followed completely in the proper order. Tests the ECU if no fault is found up until this pointĬommon mistakes when diagnosing the P0351 code Tests the primary ignition coil for proper operation if all of the cylinders are faulty Inspects the spark plug wire and plug, or the coil pack of the vehicle if the fault is with just one cylinder Uses scan tool to monitor he data stream information and determine if the fault is with a specific cylinder or all of the cylinders
Performs a visual inspection on the coil system and it's wiring, looking for any damaged or worn components Uses a scanner to check what codes are stored in the ECU, along with any freeze frame data for the codesĬlears the codes and test drives the vehicle under similar conditions found in the freeze frame data to best duplicate the faults How does a mechanic diagnose the P0351 code?
The Check Engine Light will be illuminated on the dashboard.

So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. , on the other hand, uses the factory diagrams. That saves a lot of time because you don’t have to refer back to the component locator or circuit locations. redraws factory wiring diagrams in color and includes the component, splice and ground locations right in their diagrams.

If the results show low compression, the only fix is to replace BOTH cylinder heads with the new redesigned heads now available from Ford. Ford wants you to do a running compression test and a cylinder leakdown test. The TSB states that the cause may be an exhaust valve “recession” that causes a loss of compression. Ford has issued a TSB #05-26-3 that describes a fairly significant design problem with the cylinder heads on 2004-06 Rangers with the 3.0 overhead valve “Vulcan” engine.
