2007 Ford Five Hundred Limited Sedan - Answered Questions & Fixed issues

Question moved to model category. When the Engine Malfunction Light comes on, it also generates a code to tell you exactly what is causing the problem. The Diagnostic Trouble Code (DTC) is a P???? number and can be searched online to find the cause and the fix. Currently you are in 'Limp Mode'. That is a serious fault that can severely damage your engine. Any garage will sell you the code for free. It takes less than 2 minutes. Write the code down and post it here below my Comment. DTCs https://www.google.com/search?q=2007+ford+500+awd+dtc+codes Limp Mode https://www.google.com/search?q=2007+ford+500+awd+limp+mode ..

Why would you NOT do something. Scan it. Most likely a bad wheel speed sensor.

No flasher on your vehicle ! controlled by SJB Principles of Operation The smart junction box (SJB) sends multiple voltage reference signals to the multifunction switch. When the multifunction switch is in the LH or RH TURN positions, or the hazard lamp switch is engaged, that input signal is routed to ground. When the SJB receives a request for a turn signal or hazard lamps, the SJB supplies voltage to the appropriate turn lamps.

1. Verify the customer concern.

1. Visually inspect the following for obvious signs of mechanical or electrical damage.

Visual Inspection Chart Mechanical Electrical

• Multifunction switch
• Hazard switch

• Circuitry
• Bulbs
• Rear lamp assembly
• Smart junction box (SJB)

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

NOTE: Make sure the headlamp switch is in the OFF position. NOTE: Make sure the multifunction switch is in the LOW BEAM position.

1. NOTE: Make sure to use the latest scan tool software release. If the cause is not visually evident, connect the scan tool to the data link connector (DLC).

1. NOTE: The vehicle communication module (VCM) LED prove-out confirms power and ground from the DLC are provided to the VCM. If the scan tool does not communicate with the VCM:
   • Check the VCM connection to the vehicle.
   • Check the scan tool connection to the VCM.
   • Refer to Section 418-00 , No Power to the Scan Tool, to diagnose no communication with the scan tool.

1. If the scan tool does not communicate with the vehicle:
   • Verify the ignition key is in the ON position.
   • Verify the scan tool operation with a known good vehicle.
   • Refer to Section 418-00 to diagnose no response from the powertrain control module (PCM).

1. Carry out the network test:
   • If the scan tool responds with no communication for one or more modules, refer to Section 418-00 .
   • If the network test passes, retrieve and record the continuous memory diagnostic trouble codes (DTCs).

1. Clear the continuous DTCs and carry out the self-test diagnostics for the SJB.

1. If the DTCs retrieved are related to the concern, go to the Smart Junction Box (SJB) Diagnostic Trouble Code (DTC) Index. For all other DTCs, refer to Section 419-10 .

1. If no DTCs related to the concern are retrieved, GO to Symptom Chart .

Your best bet would be to take your vehicle to a qualified repair shop !

A/C problems still David, compressor bad or system plugged.

Ac refrigerant is most likely low causing this, would need more info to tell u exactly. Other possible causes could be pressure switch, ac heat control unit, low refrigerant, bad compressor, wiring problem, if refrigerant is full would need to make sure your getting power and ground to compressor.

Check the switch on the brake pedal.

First off the cruise control is computer controlled , need to check for diagnostic trouble code's . Your vehicle has electronic throttle control also . If your don't have a factory or professional grade scan tool your odds of being able to fix this yourself is close to zero ! You could find a wiring diagram an do some voltage drop testing ,mite find lose connection . Speed Control The speed control system consists of the following components:

• Speed control switches
• Speed control deactivator switch
• Speed control indicator
• Powertrain control module (PCM)
• Electronically controlled throttle body
• Clockspring

The speed control system is controlled by the PCM. The speed control system is designed to maintain a selected vehicle speed between 48 and 200 km/h (30 and 124 mph). The speed control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, CANCEL, and RESUME), and the brake pedal. The steering wheel mounted switches are hardwired to the PCM. The speed control functions include:

• Turning the speed control system on.
• Setting and maintaining the desired vehicle speed.
• Accelerating the vehicle speed.
• Decelerating the vehicle speed.
• Resuming the prior vehicle speed.
• Turning the vehicle speed control system off.
• Canceling the speed control.

The clockspring provides the electrical interface between the steering column wiring and the speed control switches in the steering wheel. The inputs to the PCM are:

• Output shaft speed (OSS) sensor
• Speed control switches
• Stoplamp switch
• Speed control deactivator switch
• SJB messages

The outputs of the PCM for the speed control system are:

• Speed control indicator lamp
• Throttle command

The throttle position is completely controlled by the PCM through the electronically controlled throttle body. Speed control electronics are contained entirely within the PCM. When the speed control system is active, the PCM corrects for deviations in the actual vehicle speed by proportionally moving the throttle plate. The PCM modulates the throttle to minimize error between actual vehicle speed and the desired speed. The PCM strategy uses the throttle control for smooth accelerations. The PCM sends a serial message over the controller area network (CAN) to the instrument cluster whenever the speed control telltale should be turned on or off. In the event of an OFF command or a deactivation request from the deactivator switch, the speed control system carries out a hard deactivation and immediately returns the throttle to the idle position. In the event of a CANCEL command input, the system deactivates and the throttle returns to the idle position at a smooth and controlled rate. The speed control system provides self-diagnostics. The speed control system is disabled anytime an error is detected in the system. No cluster telltale or message center messages are displayed when faults occur. Fault codes are logged by the PCM. An electronic throttle control (ETC) system fault also causes the speed control system to be disabled. In this case, an ETC system warning indicator or message center message is displayed. Additionally, the following conditions cause the speed control system to deactivate:

• Transmission gear selector is put into a position other than D or OD.
• Parking brake is applied.
• Speed control set speed is over-ridden with the accelerator pedal for a period longer than 5 minutes.
• Vehicle speed loss from set speed of greater than 16 km/h (10 mph) occurs.
• Vehicle speed falls below the minimum allowable limit of 48 km/h (30 mph).
• Speed control switch is pressed or stuck longer than 2 minutes.

You have something loose in there, either a vacuum line if one or some electrical connection.

Is this chevy vehicle?? Some starters need shims when installed to prevent this type of noise when starting vehicle. If your starter had shims, put it back on nee starter..

Fuse panel should have list on it or you might have to get a manual from the dealer

Check the fuse for the radio to start.
Does the radio display light up at all? Does putting in a CD or tape turn the unit on?
If the radio doesn't turn on, it may be a bad power switch if the above doesn't work.

Built into the MAF (mass air flow) sensor. Located in the air induction system. Most likely mounted to the box that covers the air filter.

Could be bad sensor which is in hub bearing.

the ABS and traction light are on due to a failure with the speedometer. I SUSPECT A SEED SENSOR would be the culprit as if speed is not sensed from a wheel (RF / LF /RR / LR) the ABS module with be disabled and would lite the ABS and Brake light. the airbag and heated seats are on separate circuit. the air bag should be diagnosed with a handheld device ( go to advance auto or similar type parts store)n they will read the code.. post the code and I may be able to help ... also ask em to get the ABS / Brake codes a ell

Marks etched on the side.

Replace bulb

The filter should be under the car in the fuel line between the tank and the engine.
