2007 Ford F-150 5.4L Engine P0018, P0022, and P2198 Codes: Diagnosis and Solutions for Rough Idle and Power Loss

Model: 2007 Ford F-150 5.4 Fault Code: P0018 Posted: 2015-11-22 21:20

I own a 2007 Ford F-150 with the 5.4L V8 engine and am experiencing recurring check engine light issues. The truck has approximately 118,000 miles and recently started exhibiting rough idle, lack of power during acceleration, and noticeable sputtering when driving. After scanning the vehicle four times over two days, I've consistently received three diagnostic trouble codes: P0018, P0022, and P2198. Initially, a misfire in cylinder 5 was detected—after replacing the spark plug and switching the coil pack to another cylinder, the misfire code disappeared but a new 'Ignition Coil E' code (P0355) appeared. After clearing the codes and driving about three miles, the check engine light returned, and now I'm consistently seeing P0018, P0022, and P2198. The misfire and ignition coil issues have since resolved, but symptoms persist. I am seeking clear, step-by-step troubleshooting guidance without relying on professional mechanic services. Any insights into the root cause of these codes or how to resolve them myself would be greatly appreciated.

Check for a clogged or restricted catalytic converter or exhaust system on Bank 2 (driver's side). Even though this truck has straight pipes, ensure there are no obstructions in the exhaust path that could affect engine performance and trigger P0018/P0022 codes.

This 2007 Ford F-150 model comes with straight pipes and no catalytic converters or mufflers. After replacing the coil pack for cylinder 5, the truck ran smoothly for about three days before symptoms returned. The issue now appears to be intermittent—sometimes the engine runs fine, but other times it shows misfires in cylinder 5 even with a brand-new plug and coil pack. I suspect a problem with either the camshaft or crankshaft position sensor on Bank 2 (cylinder 1-8), which may be causing P0018, P0022, or ignition-related codes like P0355.

"P0355 - Ignition Coil E"\nIf this code is present, disconnect the fuel injection circuit for cylinder 5 and use a noid light to test for signal. Connect the noid light to the ignition coil's wiring harness (cylinder 5), then start the engine. If the noid light flashes, the injector circuit is working. If it does not flash, inspect the wiring from the Powertrain Control Module (PCM) to the connector for proper voltage and verify the integrity of the signal ground circuit. This procedure is based on FordTechMakuloco.com guidance.

These codes are commonly reported in 2007 Ford F-150 5.4L engines, especially with aging components and poor sensor performance.

I swapped the ignition coil for cylinder 5 with a known-good unit, but the P0355 code remained. This suggests the issue may not be in the coil itself but could involve wiring, ground connections, or internal sensor faults. Any additional troubleshooting steps would be helpful.

I experienced identical symptoms—replaced plugs, coil packs, and multiple sensors with no improvement. Eventually, I discovered that the fuel injectors were severely degraded. After pulling them apart at a local auto parts store for $10, I replaced all injector components. Since then, the truck has run smoothly without any recurring issues.
