Cruise control has not been working for a while.
Ive noticed my cruise control system not working for a while, but now that its started to get colder when I'm currenly living my trucks high idle system won't kick in. Ive read on thing to check I've done looked at what i could do before spending money on sensors. I just want to know if the systems are tied together. Thanks
My car has 242900 miles.
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hi there. First check to see if the cruise control fuse is blown. Then check the brake light switch, the brake pressure switch, the speed sensor on the transmission, or the cruise control buttons. Most of the time the brake light switch looses contact and causes the cruise control to fail. Also, the speed sensor on the transmission could be defective not allowing the cruise control to actuate. If you need further assistance with the cruise control not working, then seek out a professional, such as one from Your Mechanic, to help you.

2003 was the last year of the 7.3L Powerstroke engine being used in Ford Superduty Trucks. Stricter emissions standards resulted in a need for lower emissions and competing manufacturers were designing trucks with similar or better performance capabilities.
7.3 Power Stroke. The first engine to bear the Power Stroke name, the 7.3 L Power Stroke V8 is the Ford version of the Navistar T444E turbo-diesel V8.
Driving in heavy traffic and maintaining the correct following distance requires a lot of concentration.
The 7.3 Ford Power Stroke engine is legendary in diesel circles. It is one of the main reasons the 1999 to 2003 Ford Super Duty trucks are still so popular today. Its reliability is unsurpassed and was produced just before emissions regulations added to diesel engines` cost, complexity, and reliability.
The 7.3 Powerstroke is a two-valve behemoth which measures in at 444 cubic inches and has a maximum stock power rating of 275hp and 525lb.
Thanks to a narrowed Ford nine-inch, two-speed Powerglide and no intercooler, the 7.3L-powered dragster checks in at a lightweight (for a diesel) 2,800 pounds with Rose onboard. Inaugural passes made in the fall of 2017 yielded several nines, including a best of 9.39 at 139 mph.
Ford 7.3L combustion engine is a simple pushrod V8 with a single camshaft. Even though the setup is fairly dated by current standards, it`s proven to be highly reliable and durable.
The 7.3-liter Ford engine is available on Ford Super Duty® F-250 and F-350 trucks, while a dyno-certified version of the powertrain that returns 350 horsepower and 468 pound-feet of torque is standard on the following models: Ford F-450 chassis cab. Ford F-550.
When the system is turned on, you`ll see a white Adaptive Cruise Control icon in your cluster display or on your Head-Up Display, if your vehicle has that feature. The icon may look like a speedometer with a vehicle on top of it or an arc with a small triangle pointing through it. a.
7.3s are loud for a few reasons, most of which have to do with injection systems and block material/construction. The 7.3 uses a HEUI injection system, which uses high pressure oil to create final injection pressures within each injector individually.
Proving the 7.3L`s HEUI injection system can still run with the best of them. In the last year, each generation of the Power Stroke diesel has surpassed the 1,000hp mark on the dyno. In May 2009, the first Power Stroke to hit 1,000 hp was a 6.0L.
Aside from adding a chip, a considerable up-sizing of the fuel injectors is mandatory to get any kind of measurable horsepower out of a 7.3L Power Stroke. For us, the only option is to upgrade to a set of hybrid injectors, and specifically the 238cc version for 500hp goals.
The Ford 7.3L Powerstroke engine was produced from 1994 to 2004. Over 2 million of the 7.3L Powerstroke engines were manufactured over the decade-long production life of the engine.
However, the 2020-model work engine hasn`t had much time to prove its reliability. So, here`s all you need to know about the new monster from Ford. Ford launched its 7.3L gas V8 engine in the model year 2020 as a high-displacement work engine with low RPM and great upgrade potential.
Mid-year 1994, Ford introduced the 7.3l 444 ci Power Stroke direct-injection (DI) turbo-diesel V8. This is a rebranding of the Navistar T444E. Unlike the IDI diesels, the Power Stroke is fully electronically controlled, producing 250 hp and 505 lb-ft of torque.

Having intermittent problems with cruise control on my car
Hello. This can be caused by a number of different issues. Most of the time this is caused by a bad brake switch. If the switch is shorting out, then it will cause the computer to think that the brakes are being applied, which turns off the cruise control. If the switch is fine, then it may have a bad speed sensor or the cruise control switch itself is bad.
One of the easiest tests I do is simply have someone drive behind me and see if the brake lights are coming on without touching the pedal. If it is, then you should replace the switch. If not, then further testing of the circuit has to be done. If you need to have this done, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your cruise control problem.
Adding cruise control on a factory non equipped car.
The unfortunate truth is the dealer is correct. What you are doing is in theory feasible but not common at all. I haven’t run across anyone who has done what you are doing and I have often wondered how such an endeavor might work. My point here is, I am not surprised the dealer isn’t sure because it’s likely they have never done this themselves. The dealer doesn’t set up the PCM (Powertrain Control Module) in the cars they sell. The manufacturer does and guessing what happened when a car is being built is not common knowledge.
Anytime you modify any car, there are always details such as this that you will possibly have to address. When you choose to modify a car, you are now the engineer. The simple answer is that I can’t tell you with certainty whether or not the PCM in your car has cruise control capability. The only way to find out is to allow the dealer to check in out. Independent shops might possibly be able to, but the equipment they have is aftermarket and not produced by Mazda. The electronic equipment the dealer has is. The dealer equipment will most likely be able to do what you need.
Engine check light on and cruise control not working, but speedometer works
Hi there, thanks for writing in. Usually the P0717 OBD-II error code is associated with a speed sensor problem inside the transmission. This part helps to monitor the cruise control along with the speedometer. If the sensor is damaged or has a loose fitting wire harness, it will disable the cruise control first as a safety measure; but allow the speedometer to work in many cases. The best way to know for sure is to contact one of our mechanics to replace your speed sensor, or inspect the vehicle for cruise control issues.
Turn Signal, cruise, brakes, and emergency flashers not working properly.
If you have already replaced the flasher module for the turn signals, your problem may be in the switch assembly whether it is a shorted circuit or the contacts in the switch not making a proper connection and causing problems with other circuits. The problem with the brake lights and cruise control may be the brake light switch on the brake pedal. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at your lighting concerns and offer a more personal diagnosis.
Defrost button wont come on. Control power button doesnt work.
It seems like the defrost of the vehicle has an issue. There are several possibilities that could cause this. The control unit for the climate control system could be malfunctioning. The fuse for the rear defrost could be blown due to some unknown reason. The windshield itself could be damaged and lost connection somehow. I would recommend having a qualified professional who is proficcient in electrical diagnosis inspect your vehicle with a wiring diagram. This will help to determine where the fault in the defrost system is located. Once the issue is found, I would recommend having the issue resolved as soon as possible to prevent any safety issues that could result from lack of clear vision through the rear window.
Cruise control works only randomly
Hi there. Most of the time this is cause by a failing brake switch. The switch fails and makes the computer think that you are applying the brakes, which automatically turns the cruise off. This should be checked first. If it is fine then the computer needs to be scanned to see if there is anything else going on. If there are no codes, then it is more than likely the brake switch. If you want to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the cruise control problem.
ABS and traction control light on dash. cruise control doesn’t work.
You will have to have the ABS system scanned and not just the engine computer scanned. You will have to monitor the wheel sensors if you get no codes, but if the light is on there is a code stored in the ABS module. One of the wheel sensors is failing and will cause all the problems you’ve mentioned.
A scanner that can access the ABS of the car is needed for this diagnosis. I’d suggest getting the vehicle looked at by a qualified technician who can properly diagnose your ABS light and repair the issue as necessary.
Windshield wipers stopped working. They’ll suddenly stop working then suddenly start working again. Has been happening for a week.
The problem you are describing likely stems from an intermittent electrical fault in the wiper circuit. The windshield wiper system uses a small electric motor to move the wiper arms that you see on the windshield. That electric motor is controlled through a switch, relay, fuse, and wiring. One, or more, of those electrical components has failed although it is also possible that the mechanical arms are binding (seized, if the lubricant has dried out) thus causing the electric circuit to the motor to overload. Regardless of the underlying fault, if you request a non functioning wiper diagnostic/repair, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
