(M) Malfunction Indicator Lamp (MIL) illuminated during engine operation if this DTC was recorded (depending if required by CARB and/or EPA). MIL is displayed as an engine icon on instrument panel. (G) Generator lamp illuminated P1297 (M) No Change in MAP From Start To Run No difference is recognized between the MAP reading at engine idle and the stored barometric pressure reading. P1298 Lean Operation at Wide Open Throttle A prolonged lean condition is detected during Wide Open Throttle P1299 Vacuum Leak Found (IAC Fully Seated) MAP Sensor signal does not correlate to Throttle Position Sensor signal. Possible vacuum leak. P1388 Auto Shutdown Relay Control Circuit An open or shorted condition detected in the ASD or CNG shutoff relay control ckt. P1388 Auto Shutdown Relay Control Circuit An open or shorted condition detected in the auto shutdown relay circuit. P1389 No ASD Relay Output Voltage At PCM No Z1 or Z2 voltage sensed when the auto shutdown relay is energized. P1389 (M) No ASD Relay Output Voltage at PCM An open condition detected In the ASD relay output circuit. P1390 Timing Belt Skipped 1 Tooth or More Relationship between Cam and Crank signals not correct P1391 (M) Intermittent Loss of CMP or CKP Loss of the Cam Position Sensor or Crank Position sensor has occurred. For PL 2.0L P1398 (M) Mis-Fire Adaptive Numerator at Limit PCM is unable to learn the Crank Sensor’s signal in preparation for Misfire Diagnostics. Probable defective Crank Sensor P1399 Wait To Start Lamp Cicuit An open or shorted condition detected in the Wait to Start Lamp circuit. P1403 No 5V to EGR Sens Loss of 5v feed to the EGR position sensor. P01475 Aux 5 Volt Supply Voltage High Sensor supply voltage for ECM sensors is too high. P1476 Too Little Secondary Air Insufficient flow of secondary air injection detected during aspirator test (was P0411) P1477 Too Much Secondary Air Excessive flow of secondary air injection detected during aspirator test (was P0411). P1478 Battery Temp Sensor Volts Out of Limit Internal temperature sensor input voltage out of an acceptable range. P1479 Transmission Fan Relay Circuit An open or shorted condition detected in the transmission fan relay circuit. P1480 PCV Solenoid Circuit An open or shorted condition detected in the PCV solenoid circuit. P1481 EATX RPM Pulse Perf EATX RPM pulse generator signal for misfire detection does not correlate with expected value. P1482 Catalyst Temperature Sensor Circuit Shorted Low Catalyst temperature sensor circuit shorted low. P1483 Catalyst Temperature Sensor Circuit Shorted High. Catalyst temperature sensor circuit shorted high. P1484 Catalytic Converter Overheat Detected A catalyst overheat condition has been detected by the catalyst temperature sensor. P1485 Air Injection Solenoid Circuit An open or shorted condition detected in the air assist solenoid circuit. 25 - 12 EMISSION CONTROL SYSTEMS DN DESCRIPTION AND OPERATION (Continued) |
