Crown Victoria - Wrench Light

[@anthonykingjr4475]

I have a 08 mgm with 135k i just recently got this wrench light . Starts up fine get going down the road about 10 15 min down the road and stop at a red light wrench light comes on it shuts off I'm able to start back imd. All I get is maf and some about evap I've cleaned the maf and very recently replaced the egr and down pipe. Any idea what is going on

[@PanzerPlatform]

Right on AKJ, Thanks for watching, and the great question. I do not support parts shotgunning. Yes, it can be fun, and justified in some cases, but a proper diagnosis must come before repairs, or any parts are replaced. Theres nothing worse than that feeling of wasting money, and throwing away good parts that were actually functioning properly. Pulling a code with a scanner alone is never a reason to replace any part, it's just a starting point to begin your diagnosis. Check out the comment below from Mickey Harrington. Let me know if you need more help. -Chuck

@@PanzerPlatform I didn't shotgun parts the down pipe by egr valve split so had to replace whole unit as far as maf sensor I just sprayed it

I need to just bring it to a good shop and let them go through I bought it with 75k miles 3 yrs later it's almost at 140k

[@PanzerPlatform]

@@anthonykingjr4475 Right on, Did you read Mickey's comment? Most likely it's an electrical problem; short to ground short to power open loose connection broken wire bad connector corrosion in a connector etc. Any good shop will scan for codes, evaluate live data, and then perform a thorough visual inspection of all associated wiring based on the codes, and any irregular live data. My local Ford Dealer charges $225 an hour for electrical diagnosis. If you have a good flashlight, and and a few minutes, there's a good chance you can find the issue yourself. Would you be willing to take a look, before you take it in? -Chuck

Today i had the engine running and pressure washed the engine , omw home on the hwy it went into limp mode . Pulled to a safe place off road turned the car off for 30 min . After that time i turned it back on and it no longer illuminated. It's my only transportation. This video help point me in the right direction. Thank you

[@PanzerPlatform]

Hello, Thanks for watching. How did you fix it? -Chuck

[@WJHandyDad]

7:52 I "get" why they do that, but it's so frustrating because one broken wire and all the sensors are out

[@PanzerPlatform]

Now hang on just a second. Are you saying there was nothing wrong with the standard OBD2 protocol (pre 2008) before CANBus got involved, and just added unnecessary complexity. Blasphemous! Lol -Chuck

[@mickeyharrington6785]

Had wrench light on 2010 Grand Marquis. Broken wire going to trans pressure control solenoid. Replaced wire, light went off.

Right on Mickey, Thanks for watching, and the good feedback. By any chance do you remeber the DTC? -Chuck

Thanks I learned something today. I had seen the wrench warning light in the manual but had no understanding of what it really was. And I can assure everyone that you do not want any amount of raw fuel going through the engine and into the exhaust system. I had an 85 Dodge pickup that quit running while driving. I stopped on the shoulder and tried to start it three times with just short cranks of maybe 10 seconds. On the third crank there was an explosion under the floor. The raw fuel had hit the hot muffler and blown that thing completely open. The result was that not only did I have to replace the inexpensive ignition coil/resistor that is a little ceramic square thing that plugs into an outlet on the firewall, but I also had to replace the muffler and a piece of the exhaust pipe ahead of it.

[@DavidJones-ib3zy]

@@PanzerPlatform Sorry for the delayed update. The 'Wrench' light has not come on again & it may have been the gas cap was not tight enough , ? I got the oil changed 17 days ago so that could have been it . I checked the codes and it did not show any . Peace

[@PanzerPlatform]

@@DavidJones-ib3zy Thanks for the update. The gas cap has its own light in the dash. The wrench light does not illuminate for oil changes. It possibly an intermittent issue. So just ignore it, until it comes back on, and stays on. -Chuck

The redundancy department of the redundancy department. Excellent video Chuck. Thanks for your efforts. I am going to be in contact with a relative later today that has worked at ford garages only for the last 30 some years. I will ask him if he can provide specifics on what codes will set off the wrench light and if that includes U codes. I don't remember if I told you or not the other day but I was able to find a replacement brake light switch that is the threaded type that is 5 wire capable like the OE switch that was in the car. This may solve the P0504 finally.

[@PanzerPlatform]

Right on Mr. Black, Sorry I'm not of any "real" help. -Chuck

[@davjones2724]

My 05 MGM has the wrench light on. The transmission won't hardly move the car back or forward. I changed filter and fluid.. car still won't move like it should. Its slow to move.

[@PanzerPlatform]

Do you have a scan tool to pull the DTC codes? That would be the first step. -Chuck

I have a 2008 Grand Marquis and started having a few wiring issues....it was a damaged front end vehicle and I found some frayed wires...fixed all I could find but then the left headlight and turn signals quit working and at same time 3 warning lights on dash, ABS, brake light and 1 other in bottom left corner I changed out the wiring harness with an 07 Marquis and now it will start, but I have no lights except brake lights when I push pedal, no dinging when open door with key in or light switch on and I can't shift into gear and no dash lights

Hello, What you have described is a technician's worst nightmare. Multiple layered malfunctions over time with ineffective repair attempts complicating the issues further. I don't know where to start. Seek a competent mechanic. -Chuck

[@PanzerPlatform]

@@devontaeeason5029 Right on D, Thanks for watching. If the Wrench Light comes on, it means you have a trouble code. You will need a scan tool to pull the code. Do you have a scan tool?

[@fartmagic6074]

hello 2011 P7b102,000 miles got a wrench light and P0504 code. Car drives great after I disconnect and reconnect the battery then comes back on about 20 miles or 20 mins of driving then goes into limp mode. I replaced the brake light switch assembly and the cruise control switch. I also removed and cleaned the throttle body and changed the air filter. Car idles great no surging. I checked every fuse and checked for any vacuum leak or frayed wires. Any suggestions besides taking it to the dealer?

[@PanzerPlatform]

I just read the 9 pages of pin point testing “FD” from my service literature for P0504 on a 2011 Crown Victoria Police Model. It says the most likely cause is an open / short, or loose / corroded connector from the switch to the PCM. It walks you through checking for an open, or short from the Brake Pedal Switch to the PCM. If you take it to the dealer this is the diagnosis they will perform. It’s straightforward, and you could do it yourself with a basic multimeter.

LOL so basically it's a second check engine light that can go off for any number of reasons. Geez man.

[@PanzerPlatform]

Right on Phelcan. Yes, you are correct. lol The big difference is Federal, and State governments regognize the Check Engine Light and an "Emission" light, and will cause a failure of an Emission Inspection, or Smog Check if illuminated. Where as the Wrench Light is not regognized as an Emission Light, and will not cause a failure of a government Emission Inspection, or Smog Check. Clear as mud right? lol -Chuck
