1. Check MAPS performance.
(1) IG "OFF".
(2) Connect CH A probe to terminal 1 of MAPS and CH B probe to terminal 1 of TPS connector.
(3) Warm up the engine to normal operating temperature.
(4) Measure signal waveform of MAPS and TPS together by stepping on and off the accelerator pedal.
A. Specification :





(5) Is the measured signal waveform (Comparison response of TPS with MAPS) O.K?
YES
1) 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
1) Substitute with a known-good MAPS and check for proper operation.
