Fix the Quad drivers codes first. I had a 95 LeSlober. Codes indicated a
quad driver fault, an EGR fault, and a problem similar to yours {limp
home mode in trans). Dealer said replace the computer($200.00), replace
the EGR valve ($150.00), plus another 150 in labor. I told them
nevermind, and pulled out the schematics, and found that a fuse that fed
one of the quad drivers was EGR, and one fed the trans solenoids. I just
couldn't find the fuse. Finally found it behind the passenger side kick
panel. Replaced the fuse and all worked well. Dealer would have charged
me 500 for this. Quad drivers supply power (or grounds) to systems that
have a medium current requirement . The quad driver fault could cause
the solenoid failure. Hope this helps, James Booth

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.

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.

The problem with 2002 nissan altima is ,whenever the battery terminal is removed,the car wont accelerate,so i used my scanner to detect the faults,and it shows me some fault codes,e.g. (...


your continually removing the battery terminal is what is causing the problem
the ECM cpu program is continually being corrupted by the terminal removal and when you wipe the codes ( read it as reset the ECM) it works fine until you touch the terminal again
permanent solution is ---leave the battery terminal alone

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
