Fit L4-1.5L (2008)
Is there about 5 V?
YES - Replace the sensor that restored 5 V when disconnected.
NO - Go to step 49.
49. Turn the ignition switch OFF.
50. Disconnect ECM/PCM connector A (31P).
51. Check for continuity between ECM/PCM connector terminal A20 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM/PCM (A20) the EGR valve position sensor or the input shaft (mainshaft) speed sensor.
NO - Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the
symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
52. Measure voltage between body ground and ECM/PCM connector terminal D12.
Is there about 5 V?
YES - Go to step 58.
NO - Go to step 53.
53. Turn the ignition switch OFF.
54. Disconnect the accelerator pedal position (APP) sensor 6P connector, then measure voltage between body ground and ECM/PCM connector
terminal D12 with the ignition switch ON (II).
