Test DQ: Step 4

4) Checking FIPL Circuit For Short To Power  Turn ignition switch to "OFF" position. Wait 10 seconds. Turn key to "ON" position with engine "OFF". Disconnect ECA 60-pin connector. Inspect for damaged pins, corrosion, or loose wires. Repair as necessary. Install breakout box. With ECA and FIPL disconnected, set DVOM at 200,000 ohms. Measure resistance between pin No. 47 and pin Nos. 26 and 57 at the breakout box. If each resistance is greater than 10,000 ohms, replace the ECA and perform the QUICK TEST. If not greater than 10,000 ohms, repair short, remove breakout box, reconnect all components and repeat the QUICK TEST. the original Code 32 was the result of the original EVP sensor. Service EVP sensor and repeat QUICK TEST.
