#### TESTING

##### 1991 Models

1. Using a suitable ohmmeter, check the resistance cold between the terminals of the signal generator.
2. The signal generator (pick-up coil) resistance cold should be as follows:
   - NE–G- — 180–220 ohms
   - G1–G- — 140–180 ohms
   - G2–G- — 140–180 ohms
3. If the resistance is not correct, replace the distributor housing assembly.

##### 1992 Models

1. Using a suitable ohmmeter, check the resistance cold between the terminals of the signal generator.
2. The signal generator (pick-up coil) resistance cold should be as follows:
   - NE–G- — 155–240 ohms
   - G1–G- — 125–190 ohms
   - G2–G- — 125–190 ohms
3. If the resistance is not correct, replace the distributor housing assembly.

##### 1993–95 2TZ-FE Engines

1. Using a suitable ohmmeter, check the resistance cold between the terminals of the signal generator.
2. The signal generator (pick-up coil) resistance cold should be as follows:
   - NE–G- — 155–250 ohms
   - G1–G- — 125–200 ohms
   - G2–G- — 125–200 ohms
3. If the resistance is not correct, replace the distributor housing assembly.

##### 1995–97 2TZ-FZE Engines

1. Using a suitable ohmmeter, check the resistance of the signal generator.
2. Pick up coil resistance should be as follows:
   - 1995 Cold — 125–200 ohms
   - 1995 Hot — 160–235 ohms
   - 1996 Cold — 135–220 ohms
   - 1996 Hot — 175–255 ohms
   - 1997 Cold — 125–200 ohms
   - 1997 Hot — 160–235 ohms
3. If the resistance is not correct, replace the distributor housing assembly.
