Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
PINPOINT TESTS A, AA, AAA, B and C are intended to diagnose hard faults. Intermittent failures may be difficult to diagnose using these procedures. Following information should be noted during testing:
- All voltage readings given in test procedures are based on values obtained using a standard DVOM such as Rotunda (007 -00001) or Fluke (20 or 70 Series). DO NOT use RMS type meter.
- When instructed to inspect a wiring harness, perform both a visual inspection and a continuity test.
- When making voltage checks, ground connections should be made at negative battery terminal or cast iron surface of engine.
- When making measurements on a wiring harness or connector, perform a wiggle test while measuring.
- When making voltage checks, ground readings are defined as a value of less than 1.0 volt. Battery voltage is defined as a value of more than 10 volts.
- Circuits are identified in all capital letters; for example: PIP. Manufacturer's breakout box overlay test terminals are identified by a "J" prefix; for example: J15 (PIP). This indicates test terminal number and circuit identification. Probe models may not have a "J" designation in front of the test terminal number.
- Test procedures are intended to identify faulty components or wiring while fault is present. If complaint is intermittent condition, refer to TESTS W/O CODES - EEC-IV (2.0L) article.
| Application | Pinpoint Test/Step |
|---|---|
| No Start & No Codes Present | AA/1 |
| No Start & Code 211 Or 212 Present (PIP At PCM Fault) | AA/1 |
| Vehicle Runs Normal Until SPOUT | AAA/1 |
| Code 212 (Engine Runs, IDM Missing | B/1 |
| Code 213 (Timing Incorrect, SPOUT Open, Poor Fuel Economy Or Poor Driveability) | C/1 |

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
