EG–566 ENGINE – 2JZ–GTE ENGINE TROUBLESHOOTING INSPECTION PROCEDURE 1 Check voltage between terminal EGR of engine control module connector and body ground. SST ECM B 75 EGR FI6620 P (1) Connect SST (check harness "A"). (See page EG–510) SST 09990–01000 (2) Warm up engine to normal operating temperature. C Measure voltage between terminal EGR of engine control module connector and body ground. OK Voltage: 9 — 14 V NG OK Go to step 4 . 2 Check resistance between terminals of VSV for EGR. P11360 P Remove VSV for EGR. (See page EG–310) C Measure resistance between terminals of VSV for EGR. OK Resistance: 30 — 34 Ω at 20˚C (68˚F) OK NG Replace VSV for EGR. 3 Check for open and short in harness and connector between EFI main relay and VSV for EGR, VSV for EGR and engine control module (See page IN–30).
