Component Inspection
1.

Check MAPS performance.

(1)

IG "OFF".

(2)

Connnect 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 accellerator padel.

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

YES

a.

Many malfunctions in the electrical system are caused by poor harness(es) and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage. So, check poor connections and the related circuit between ECM and component thoroughly. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

NO

a.

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

If the problem is corrected, replace MAPS and go to "Verification of Vehicle Repair" procedure.
