So you are saying the bulb for the check engine light is burned out and needs to be replaced ??
And the trouble codes you listed are for lean fuel mixture which could point to a vac leak or low fuel pressure.

SOURCE: failed smog cause check engine light

I can tell you for sure that all US models of the Ford Ranger came with a emission system that incorporated a MIL or check eng light, go to the dealer and have them run your VIN on the Ford on line information service, that will give you the engine Calibration of the emission system, you can then find out what emission system was used, export or US.

171 and 174 are engine running lean. Repair cost will depend on cause. Check for vacuum leaks. Start by checking for vacuum lines coming off the engine intake manifold. Make sure they are all attached at both ends and are not cracked, etc. These engines have a lot of intake manifold gasket issues. Spray carb cleaner or starter fluid at the gaskets with the engine running. If the engine revs at all, you have leaky gaskets. This is a bigger job to fix--a few hours labor.

153 and 1151 is an O2 sensor. About $150 bucks to fix that.

If you have more questions, please let me know.

Failed emission. BMW 325 Ci. MIL CMD failed. KOER fail. What does it mean?


There is a problem with the way the engine is burning fuel also the check engine light bulb is out..In otherwords when a car is inspected and put on the analyzer. It runs tests of various systems. In your case KOER means your check engine light is supposed to come on when you crank the car and go off once the car starts. Yours never came on as a check (maybe bulb out ) or intentionally disconnected. Also your care is putting out emissions above the limit.

What does mil cmd fail mean?


MIL is your malfunction indicator lamp, (check engine light)

CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer

check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.

Where is thr EEC IV on a 1991 Ford F150 6 cylinder?


EEC-IV: Ford's fourth-generation EEC system; its first to incorporate on-board diagnostics (OBD) & memory to store diagnostic trouble codes (DTCs). Their chips are soldered to their boards (meaning they can't be removed to change performance characteristics like some other manufacturers), but later versions include flash-programmable memory (EEPROM).

According with the Repair Manual, for 1991 Ford Truck F150 4.9L FI 6cyl, the Electronic Engine Control (EEC) or Engine Control Computer is located in seating area, driver side, behind dash, upper corner, mounted on dash support brackets.

How the Malfunction Indicator Lamp (MIL) Operates:
A. System OK
The Malfunction Indicator Lamp (MIL) is turned on as a bulb check when the ignition key is first turned on. The EEC-IV processor turns the bulb off as soon as it receives the PIP (cranking) signal.

B. System Not OK
If the Malfunction Indicator Lamp (MIL) should remain on after the vehicle has started, run Quick Test and has had service any DTC's. If Self-Test has pass DTC's, the (MIL) is always on, and the vehicle has no drive symptoms, go to "Section 2A"

If the MIL never comes on, go to "Section 2A".

If the vehicle is a no start, go to Pinpoint Test Step

NOTE:
When in Self-Test the MIL is not limited to Continuous Memory Codes and will also flash other DTC's. Also, Continuous Memory Codes are erased from Continuous Memory if the original fault has not occurred in the last 80 warm-up cycles (40 cycles on some applications).



Hope this helps.

Hi, I have a 2007 Dodge Sprinter & am getting an alert code P2015. It's apparently a sensor malfunction. Can you tell me which sensor is affected by this trouble code?


Code Description onepxblk.gif P2015 Fuel Rail Pressure Sensor Signal Too Low - With Automatic Transmission arrow_right_blacks.gif Printer Friendly P2015 Fuel Rail Pressure Sensor Signal Too Low - With Automatic Transmission Possible Causes Setting Conditions
  • Check for air in the Fuel system
  • Check the fuel pressure
  • Check for leaks in the Fuel Supply system components
  • Fuel pressure solenoid has failed
  • Fuel quantity solenoid has failed
  • Fuel pump has failed
  • Fuel supply is contaminated
Engine running; and the ECM determined that the fuel rail pressure was too low for a given engine speed and load.

This code sets in 1 Trip(s).
This code will turn on the MIL (Malfunction Indicator Lamp) onepxblk.gif Malfunction Indicator Lamp The Malfunction Indicator Lamp (MIL) alerts the driver that the Powertrain Control Module (PCM) has detected an OBD II emission-related component or system fault. When this type of malfunction occurs, an OBD II Diagnostic Trouble Code (DTC) will be set by the PCM. The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON, or is identified with an ISO standard engine symbol (i.e., a picture of an engine).
Bulb Test
Each time the ignition switch is turned to the "on" position, the MIL indicator is illuminated for about 3 seconds (which is a function of the PCM).
MIL Lamp-On Message
Each time the PCM detects an Emissions related fault, the MIL is illuminated to inform the driver that the vehicle needs to be taken in for service.
onepxblk.gif COMPONENT MONITOR DRIVE CYCLE INSTRUCTIONS
  • Do not turn off the ignition switch during the test procedure.
  • All Onboard System Readiness codes are cleared if the battery is disconnected or when the Powertrain Control Module (PCM) is cleared with the scan tool.
  • This drive cycle can be used to determine if the Readiness code for this Monitor will run and complete, and if the Malfunction Indicator Lamp (MIL) will remain off after the vehicle is driven.
  • Operating Ranges: Whenever a range of values is provided, try to operate the vehicle in the middle of the range. For example, if the vehicle speed range is from 45-65 mph, operate the vehicle at as close as possible to 55 mph. If the Short Term fuel trim range is -20% to +20%; try to operate the vehicle near 0%.
  • Scan Tool Data: There are certain Parameter Identification (PID) values that must be within range before this Monitor will "run". It can be helpful to pull up those PID items on the scan tool so an assistant can view them during the test.
  • The Readiness code for this Monitor defaults to "continuous" or "monitoring" because this Monitor runs continuously when the engine is cranking or running.
  • This information is a representation of a Drive Cycle, and may vary due to software revisions to the PCM.
COMPONENT MONITOR PRETEST CONDITIONS
  • MIL is off.
  • Battery voltage between 11-16v.
  • Key on or engine running at idle or cruise speed.
TEST PROCEDURE
  1. Connect the scan tool to the data link connector (DLC).
  2. Start the engine and allow it to run at idle speed for 1-2 minutes.
  3. Accelerate at part-throttle to Cruise speed and maintain that speed for several minutes. Bring the vehicle to a stop, but do not turn off the ignition key.
  4. Check for any diagnostic trouble codes (DTC's) in memory. If any DTC's are set, refer to the appropriate trouble code chart to make the repair. If no DTC's are set, the test is finished. Return to the service bay and turn off the ignition key.

Emmissions failed due to the following. OBD Connector Integrity - malfunction indicator light (MIL) status This is for a 2000 chevy lumina


MIL status is error codes, but usually for pre 1995 vehicles. If you check engine light was on, then it would not pass emmissions. Since your vehicle is a 2000, I would suggest you take it by an autoparts store and have them read your error codes before you try to reset them. Make sure you write them down in the order they come off their scanner.

Yu can usually clear error codes by disconnecting your battery.

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
