MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 1122 - Intake Manifold Pressure Sensor Circuit Failure - Continued 6. Disconnect all sensors from sensor harness except intake manifold pressure sensor. Reconnect sensor harness connector to ECU. 7. Disconnect coolant level sensor jumper wires. Install breakout cable. Place ignition switch in ON position. 8. Check intake manifold pressure sensor signal voltage. Check voltage between leads C and B of breakout cable. Voltage should be 0.70-1.40V If voltage is not as specified, proceed to following steps. 9. Place ignition switch in OFF position, disconnect sensor harness from engine ECU, and disconnect all sensors and coolant level jumper wires no. 5 and 6. Disconnect intake manifold pressure sensor. a. Measure resistance from sensor harness connector pin 40 to all other pins in connector. Resistance should be greater than 100k ohms. If engine harness requires replacement, notify SRA. A B C 0.70-1.40V
