Check engine light is on ( solid ) and not enough power while driving. What could be the problem?


If the check engine light is on then there is a problem in the engine or transmission or a related system. You may be in what is called "LIMP" mode. What needs to be done is have the dealer or a well equipped shop run a fault code test and do the diagnostics associated with the code or codes.

Engine light stays on 2003 chev venture


This indicates that there's a fault in the engine and/or it's related sensors that needs to be addressed. You must have your vehicle scanned and have the diagnostic trouble codes retrieved. This will pin point the area affected in the vehicle and give you a starting point. Post codes for further assistance.

CODE P1870,P0420


P1870 generally means that the transmission is slipping. P0420 relates to an issue with a vehicles catalytic converter. To know specifically what each code is, as it relates to your vehicle, you should take it to a local auto-part store (like AutoZone and have them pull the codes off of your vehicle. At auto part stores, they generally do this service for free and it is pretty quick. Regards ~ JD

Car cannot accelerate above 2000rpm. engine check light on


Have someone (most auto parts stores will do this for free) put a code reader to the vehicle which will pull up a error code indicating what the general reason for this is--they can also with that unit clear the code so you can try vehicle again to see if code repeats or not.

Any good repair center can and will do this first thing.

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.

P0780 Automatic Transaxle Malfunction - With Automatic Transmission





Possible Causes


Setting Conditions







  • Mechanical problems present in the automatic transmission can cause this code to set. See the note below.


  • Refer to the repair instructions in a transmission repair manual or the information in other electronic media to repair this code.




Engine running; vehicle driven at Cruise speed, and the PCM detected a problem in the mechanical operation of the automatic transmission. Note: This trouble code (P0780) sets with along with several TCM related trouble codes.he





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).

Readiness Codes

To check if the Readiness Codes are set to complete, turn the ignition switch "on", but do not start the engine. The MIL will come "on" for 15-20 seconds. If it then goes "off", the Readiness Codes are set to complete, If it flashes five times, one or more of the Readiness Codes are not set to complete. To set Readiness Codes from incomplete to complete, perform the drive cycle procedure for the appropriate code.

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.




COMPONENT MONITOR DRIVE CYCLE INSTRUCTIONS



  • Do not turn off the ignition switch during the test procedure.


  • All Onboard Diagnostic Monitors are cleared when 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 MIL will remain off after the vehicle is driven.


  • Operating Ranges: When a range of values is provided, try to operate the vehicle in the middle of the range. For example, if the vehicle speed range calls for 45-55 mph, drive the vehicle as close as possible to 50 mph. If the engine speed should be 1,000-2,000 rpm, try to operate the engine at 1,500 rpm.


  • 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 testing.


  • The Readiness code for this Monitor defaults to "continuous" or "monitoring" because this Monitor runs continuously when the engine is cranking or running.




COMPONENT MONITOR PRETEST CONDITIONS



  • MIL is off.


  • No Emission related DTC's are present.




TEST PROCEDURE



  1. Connect the Scan Tool to the data link connector (DLC). Use the Scan Tool to clear any stored DTC's and to reset the OBD Monitors.


  2. Start the engine and allow it to run at idle speed for 15 seconds.


  3. Accelerate at part-throttle to 40 mph and maintain that speed for several minutes. Bring the vehicle to a stop, and then allow the engine to idle with the transmission in Drive (in Neutral for M/T) for 15 seconds.


  4. Then accelerate at moderate throttle to 50 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop, and then accelerate to 40 mph and maintain that speed for 15 seconds. Bring the vehicle to a stop and allow the engine to idle for 15 seconds. Repeat this step at least 5 times.


  5. Check for any Pending codes in the Generic OBD II section of the Scan Tool. If no Pending codes are set, the Component Monitor test is complete. If any Pending codes are set, refer to the appropriate trouble code repair information to make the repair.
