What does low oil pressure on 2008 Chevy Impala 3.5 V6 LS


Do you mean what causes low oil pressure? This is a very reliable engine for the most part. If the oil light is on or gauge is reading low, have the oil pressure sensor inspected for failure. These sensors do go bad.

What is a po532 code on a 2008 hhr ss


DTC P0532: Air Conditioning A/C Refrigerant Pressure Sensor Circuit Low Voltage.
The engine control module (ECM) monitors the high side refrigerant pressure through the A/C refrigerant pressure sensor. The ECM supplies a 5-volt reference and a low reference to the sensor. Changes in the A/C refrigerant pressure cause the sensor signal to the ECM to vary. When the pressure is high, the signal voltage is high. When the pressure is low, the signal voltage is low. When pressure is high, the ECM commands the cooling fans on. When pressure is too high or too low, the ECM will not allow the A/C compressor clutch to engage.

My low pressure fuel pump on my e270cdi cut out under high load conditions.no pressure from the rear.all fault codes tell me the rail pressure is to low


Fuel pump relay is in cavity A in the rear SAM ( Signal Acquisition Module.) on the left hand side of the trunk behind a door.

When did you check the voltage..... you must read it while cranking or you will get a zero voltage reading.. The low pressure tank pump builds pressure to the high pressure pump and then shuts down until a pressure drop is sensed in the low pressure line and it then starts up again.

If rail pressure is too low, it often is the high pressure pump in the engine or the relief valve in the fuel rail. The tank pump is low pressure just to stop the tandem pump from cavitating by sucking too hard.

Mercedes can check the rail pressure and do an injector pressure drop to rule out a leaking injector.

If the tank pump is bad it will require replacement.

Just want to make sure that the a/c low pressure line is located high is the a/c low pressure located in the back of engine compartment and high for easy access


Typically the the low pressure/suction line is a bigger pipe/tube, as far as location it depends on the car. The bigger AC line is almost 99 percent of the low pressure. Usually on the cap it will say most of the times to there is a different hydraulic fitting for the low and high side. Most cars I have seen have a little tag that will say suction or low pressure line, and or discharge high pressure.

If you are re charging the gas, always use the low pressure side of the system.

Low oil cause low oil pressure


No, the oil level nothing to do with the pressure.
If you have low pressure, check the sender unit, check the pressure with a mechanical gauge, if still low, check the pump

Low presure oil


first thing check is the engine oil level.if oil level okay check oil pressure should be for the 4.2 engine oil pressure should be 12 psi @ 1200 rpm for the 5.3 oil pressure should be 18 psi @ 2000 rpm if oil pressure good problem in the oil pressure sending unit. if oil pressure is low problem faulty oil pump or worn crankshaft bearings if oil pressure low engine will have rod knock.make sure you are using correct oil viscosity if oil too thick you will have low oil pressure oil too thin you will loose oil pressure.

Uses too much fuel, started since i got here from seattle now in enigma Ga, dealer did not fix the problem


You may be experianceing exhaust problems.The catalytic converter may need to be replaced,it will make any vehicle hard on fuel because thet can't get rid of exhaust as fast as they are demanding more fuel,resulting in wasted fuel out the pipe.

YOU NEED 28 PSI ON LOW SIDE AND ABOUT 190 ON HIGH SIDE.YOUR REFRIGERANT IS LOW THAT WHY COMPRESSOR CYCLING ON AND OFF.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
