Probably bad oxygen sensorĢ2 Coolant sensor signal out of range – May have been disconnected to set timingĢ3 Incoming air temperature sensor may be badĢ5 Automatic Idle Speed (AIS) motor driver circuit shorted or target idle not reachedĢ6 Peak injector circuit voltage has not been reached (need to check computer signals, voltage reg, injectors)Ģ7 Injector circuit isn’t switching when it’s told to (TBI) 16V or over 4.96Vġ6 Loss of battery voltage detected with engine runningġ7 Engine stays cool too long (bad thermostat or coolant sensor?)ġ7 (1985 turbo only): knock sensor circuitĢ1 Oxygen sensor signal doesn’t change (stays at 4.3-4.5V). Older Model Computer Codes (OBD-I) – IMPORTANT! Codes may be different for newer vehicles starting circa 1996.ġ1 No ignition reference signal detected during cranking OR timing belt skipped one or more teeth OR loss of either camshaft or crankshaft position sensor.ġ2 Battery or computer recently disconnectedġ3 MAP sensor or vacuum line may not be workingġ4 MAP sensor voltage below. If this method does not work, try the OBDI method. It will then show the error codes (it might show them starting with P).

The odometer will go through 1111111 through 999999, then display the car’s serial number. Newer (OBD-II) models – Put the key into the ignition, push down the odometer reset button, then turn the key to RUN with your finger on the button – and then release the button. It will never flash more than 9 times, so watch for those pauses!
#OBD AUTO DOCTOR 2000 JEEP WRANGLER CODE#
Each code is a two digit code, so a (for example) 23 would be FLASH FLASH (pause) FLASH FLASH FLASH (long pause).

(“On” is NOT “Start” and “Off” is NOT “Lock”). Within five seconds, switch the key on, off, on, off, on. Older (OBD-I) models – Start with the ignition off. One major symptom of this is losing third and/or fourth gear on autos. “key trick”) to get the codes, a few things to note:ġ) You may have to set the parking brake for the codes to showĢ) On older models, the blink-spacing is not always perfectly uniform, so if you see 23 23, it’s probably just a single 55 since codes are not repeated (55 is end of codes – it’s normal)ģ) On newer models with a digital odometer, the codes are usually displayed on the odometer rather than blinking the check engine light.Ĥ) When the computer indicates major failure, it can activate “Limp In” mode, which guesses about data to compensate for sensor failure, allowing you to get the car to a mechanic. So, before outlining the proceedure (a.k.a.
