What sensors can be disconnected and not cause a check engine light I have high Idle and just read about the power steering sensor?
On almost all cars any sensor unplugged can turn on the check engine light.
What is check engine code P0520?
P0520 Code Engine Oil Pressure Sensor/Switch Circuit Malfunction
Can you do a compression check on a engine with the exhaust disconnected?
yes
Please help Check engine light came on and notice a gas odor?
Check your gas cap. If the tank does not build pressure, it trips a sensor and the check engine light will come on. The gas smell is the fumes that should have created the pressure.
Why would your check engine light come on after replacing the water pump on my 96' Chevy Lumina?
Replacing the water pump will not cause the check engine light to come on. Either it is a coincidence or you have accidentally disconnected a wire or damaged a sensor somehow.
Where is the oil pressure sensor on a 2001 Lincoln Navigator?
Oil Pressure Sensor Testing 1. Test and verify the engine oil pressure. If no or insufficient pressure exits, oil pressure problem exits and gauge and sensor are operational, repair oil pressure problem. 2. Check the appropriate fuse before attempting any other diagnostics. 3. Unplug the sensor electrical hardness. 4. Using an ohmmeter, check continuity between the sensor terminals. 5. With the engine stopped, continuity should not exist. Ø The switch inside the oil pressure sensor opens at (6) psi or less of pressure. 6. With the engine running, continuity should exist. 7. If continuity does not exist as stated, the sensor is faulty.
Can air idle control valve make run rich?
No it will not; Need to check MAP sensor, coolant sensor, fuel pressure regurlator Mass air flow sensor if it has one. IS CHECK ENGINE LIGHT ON ??? If so scan engine with scanner. GOOD LUCK.
What does check engine code P0071 for a 2006 Dodge Grand Caravan mean?
P0071=Ambient Air Temperature Sensor Range/Performance. There is a temp sensor in the fresh air intake that monitors the ambient air temp coming into the engine. Check to see if it is disconnected. On this van, the ambient temperature sensor is located in front of the bottom of the ac condenser.
What does error code P0470 for the check engine light mean?
P0470 is Exhaust back pressure sensor malfunction.
How much to replace oil pressure sensor?
They are easy to change. Here is an article on how to test them. Oil Pressure Sensor Testing 1. Test and verify the engine oil pressure. If no or insufficient pressure exits, oil pressure problem exits and gauge and sensor are operational, repair oil pressure problem. 2. Check the appropriate fuse before attempting any other diagnostics. 3. Unplug the sensor electrical hardness. 4. Using an ohmmeter, check continuity between the sensor terminals. 5. With the engine stopped, continuity should not exist. Ø The switch inside the oil pressure sensor opens at (6) psi or less of pressure. 6. With the engine running, continuity should exist. 7. If continuity does not exist as stated, the sensor is faulty.

Why does your 87 fiero gt bogs out when its given gas?
Possibilities:Ignition: check plugs, cap rotor etcFuel pressure, Failed fuel pump or regulator, Check pressure at port.Control system readings incorrect. Need to get car onto a scanner and see what readings are out of calibration. Throttle position sensor, MAP sensor (Manifold Absolute Pressure), O2 Sensor could cause this if it is disconnected or way out of rangePlugged exhaust system, Muffler or Catalyst or has some one stuffed something in the tail pipes?Plugged air cleaner.Internal engine problem like a bad camshaft
