Remedy 7

1. Remove mounting screws from front sensors and proceed as follows:
a. Using wire brush or blunt thread tap, clean threads of rivet nut and contact surfaces between sensor and bracket on body. Do not use chemicals of any kind.
b. Lubricate threads and receiving hole in rivet nut.
c. Lubricate threads of new mounting screw, then install front sensors.
d. Erase fault code and wait for at least 35 seconds with ignition switch On. If fault code persists, proceed to step 2.
2. Check connector H4-10 (H4-11) and H3-16 (H3-17) for poor contact. Erase fault code and wait for at least 35 seconds with ignition switched On. If fault code has been cleared, the fault could have been in either of the connector H4-10 (H4-11) and H3-16 (H3-17). If fault code persists, proceed to step 3.
3. Disconnect H4-10 (H4-11). Using an ohmmeter at connector H4-10 (H4-11), measure wiring resistance to front sensors as follows:
a. On front sensor 1, measure between pins 1 and 3.
b. On front sensor 2, measure between pins 1 and 2.
c. If resistance is equal to or greater than 1.9 ohms, the fault could be in wiring between connector H4-10 (H4-11) and H3-16 (H3-17) or in wiring between connector H3-16 (H3-17) and front sensor. Proceed to step 4. If resistance is lower than 1.9 ohms, proceed to step 5.
4. Disconnect H3-16 (H3-17). Using an ohmmeter at connector H3-16 (H3-17), measure wiring resistance to front sensors as follows:
a. Measure between pins 1 and 3.
b. If resistance is lower than 1.9 ohms, the fault is in the wiring between connectors H4-10 (H4-11) and H3-16 (H3-17).
5. The fault code could be in wiring between connector H4-10 (H4-11) and electronic unit.
