The PDF contains decision trees that save hours of guesswork:
| Symptom | Diagnostic Steps (from manual) | | :--- | :--- | | P0300 Random misfire | 1. Swap coils (cyl 1→4). 2. Check fuel pressure (38–44 psi). 3. Inspect camshaft reluctor ring for cracks. | | P0010 DVVT circuit | 1. Measure OCV resistance (6.9–7.9 ohms at 20°C). 2. Apply 12V to OCV – should click. 3. Check oil pressure at phaser. | | P0171 Lean (bank 1) | 1. Inspect intake manifold gasket (rubber hardens). 2. Check purge valve stuck open. 3. Clean MAF sensor (housed in air cleaner lid). | | Overheating at idle only | 1. Test fan relay via ECU pin E5-6. 2. Verify coolant temp sensor resistance (2.3–2.6 kOhm at 20°C). 3. Replace radiator cap (0.9 bar). |
