SOURCE: running rough

get rid of this car sir, its a lemon. With everything you've changed the only thing left is checking parimeters on a scan tool for the senors. But you gotta know what your looking at.

SOURCE: oil pressure light on at idle for Volvo S40 MY2005 B5244S4 Engine

Since you are going to check the one way valve and cleaning the filter too, I would recommend to check the intake air filter and clean it throughly. After that use carb cleaner to free up the nozzles of the injector valve . If the engine sound better after using carb cleaner, add some into the fuel from the fuel filter or pump, whichever one has easy access, and gun your engine in short bursts, after which it should run better.........sodeep

SOURCE: I changed the hydraulic gear pump on my bobcat and had an AHC code light up. Before finishing my repair I started the machine and checked for hydraulic fluid leaks by letting it idle for a few minutes

Disconnect the battery for 30 minutes. On cars , this resets the computers. Back to factory specs. Worth a shot. If the sensor worked before, most likely it is good.

Testimonial: "I disconnected the battery and lifted the seat to clear anything that would cause the AHC code. The AHC is a safety feature that helps make sure there is weight in the sat before it will allow operation. If I understand correctly. your idea cleared the code but upon movement of the bobcat it reappeared"

SOURCE: I have a 90 763 bobcat when it gets cold I go to start it and the hydraulics won't kick out it stays engaged if I shut off the key for 5 times then it'll turn over and the hydraulics grab again butif

I would guess that there might be a bad control valve and the fluid is cold ...and leaking by the valve and engaging the drive train...good luck.

SOURCE: My 2002 TB a/c works for 20 min. Then does not. Checked , no leaks, clutch turns, condenser clicks until blowing hot air, replaced low pressure switch

Something to check because this has happened to me.....Make sure you have enough coolant in the radiator/overflow tank. IF the engine is running hot, the thermal switch on the AC compressor will turn it off to protect the compressor from overheating and damaging it. Don't go by the guage in the dash, it's usless. Hook up a scan tool and get the exact temp. Shouldn't be over 210 which is normal operating temp.

I have a 753 f series bobcat and the lift and tilt stop working after about a minute after start up. its like it stops working after the pressure builds up.


problem flow control valves locking off flow
they are valve used in hydraulic to control the operation of hydraulics should a hose or cylinder fail by blocking of flow if it exceeds a set rate
discus it with the technician to determine if they are faulty and to get a proper diagnosis

How do I replace hydraulic line from pump to right arm on my 96 753 bobcat


to replace hoses on hydraulic equipment you have to have all the parts in the relaxed position clean the area of the connections so that dirt will not get into the system.

that is the bucket on the ground, allowed to tilt forward

nothing can be held under hydraulic pressure

the engine should be shut off

use spanners to undo hose fittings (no hands)

ensure a safe work procedure and wear rubber gloves , eye ware ,face shield and keep hands away from connections ---oil under pressure can penetrate the skin and cause immediate death ---

once you have the hose disconnected replace it with a new hose

after fitting the new hose and tightening the fittings ,start the engine and cycle the hydraulics as this eliminates the air in the system

My bobcat 553 wont start unless i jump the starter and then the hydraulics still dont work


have a load test done on the battery to check for a dead cell. IF the battery is dead then there will not be enough current to work the electronic controlled hydraulic valves . I imagine this machine has joy sticks for controls and not linked levers to the valves.

Diagnostic code P1782


P1782 DODGE - 2/4-OD Pressure Switch Circuit Possible causes of this code are: - Low transmission fluid level (check level hot transmission only)
- Dirty transmission fluid (has transmission been serivced at least every 60,000 miles, fluid and new filter?)
- Faulty 2/4-OD Pressure Switch
- 2/4-OD Pressure switch poor electrical connection
- 2/4-OD Pressure switch circuit is open or shorted
P1782 DODGE Description The pressure 2/4-OD Pressure Switch is part of the pressure switch of the transmission. The pressure switch are located in the solenoid assembly. The switch provide input information to the Transmission Control Module (TCM). The switch will inform to the TCM is pressure exist in a specified hydraulic circuit. the TCM uses this information to verified that the solenoids are working or not.

DTC P0089 ( FUEL PRESSURE REGULATOR) Code is active. The Jeep wont pass 3000rpms and is very short on power. Problem goes away when you switch it off and back on, but it comes baack when hot and sitting at...




The fault code relates to the fuel pressure sensor, it is either detecting low pressure, or is faulty.

It is most likely low pressure, either caused by an injector excessively leaking back through the leak off system or the pump is not pumping hard enough.

Start by getting a leak back test done on the injectors, and also a rail pressure test, if both come back as ok, then it is most likely the sensor that is faulty.

good luck

!991 Jeep Wrangler clutch pedal loses pressure. I have to pump it to get enough pressure to shift. I keep it full of brake fluid. I can see no leaks. Thanks for any help.


leaky slave or master cylinder - if you have someone listen to the slave cylinder while you press the pedal is should "squelch" if there is air in there, if the slave cylinder doesn't make a squelching sound then the master cylinder or a hydraulic line between the two cylinders is leaking - slave cylinder isn't very expensive but the master cylinder can be rather pricey. and any good parts shop or motor-factor can source or make-up a new hydraulic line if it is the line itself that is leaking.
