Error code p0650


OBD II codes are specific to manufacturers and often specific vehicles. A Hyundai Accent P0650 may not be the same as a Hyundai Sonata P0650 because Hyundai loaded more diagnostic codes into the upscale Sonata.

Check with AZone or similar, they'll tell you the code description, and give you possible suspect causes to check.

Fail smog0due to code p0650 g mil


Code 650 is for a problem with the check engine light circuit.
It could be something in the computer, but chances are the bulb in the cluster is out. You may have to remove the cluster to replace the bulb.

My 99 Jeep Wrangler failed inspection for a P0650 mil malfunction. Is this a wiring problem or a bad bulb/fuse?


DTC P0650 represents an issue with the actual check engine light (malfunction indicator lamp). Ignition voltage is supplied directly to the malfunction indicator lamp (MIL). The powertrain control module (PCM) controls the lamp by grounding the control circuit via an internal switch called a driver. The primary function of the driver is to supply the ground for the component being controlled. The driver has a fault line which is monitored by the PCM. When the PCM is commanding a component ON, the voltage of the control circuit should be low, near 0 volts. When the PCM is commanding the component control circuit OFF, the voltage potential of the circuit should be high, near battery voltage. If the fault detection circuit senses a voltage other than what is expected, the fault line status will change causing the diagnostic trouble code (DTC) to set.

A DTC P0650 indicates a problem with the circuit to the actual check engine light itself. If the fault is current, check if the check engine (service engine soon) lamp comes on when you turn the ignition on, If not, we will need to pull the engine control computer and ground the wire that goes to the light. If the light comes on, it is a failed pcm which must be replaced and reprogrammed. If not, it is either the circuit to the cluster or the cluster itself.

Good luck.

What does code 1-p0650 mean?


P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:
  • Harness or connectors (MIL circuit is open or shorted.)
  • MIL bulb may be faulty
