(1)

IG "OFF".

(2)

Connnect CH A probe to terminal 1 of MAPS and CH B probe to terminal 1 of TPS connector.

(3)

Is the measured signal waveform(Comparison response of TPS with MAPS) O.K ?

YES

a.

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "Verification of Vehicle Repair" procedure.

NO

a.

Substitute with a known - good MAPS and check for proper operation.
