Have a code po26 code


This code means that either the throttle position switch, or its wiring is shorted. So the system should be inspected and tested to see whether the problem is in the switch or the wiring. When the short is found it should be repaired, or the defective part replaced.

I have 4 codes that came up on my 2005Chevy impala, PO 128,PO336,PO38,and PO 386can anyone tell what these are?


P0038 - HO2S Heater Control Circuit High Bank 1 Sensor 2
P0128 - Coolant Thermostat (Coolant Temp Below Thermostat Regulating Temperature)
P0336 - Crankshaft Position Sensor Circuit A Range/Performance
P0386 - CKP Sensor B Circuit Performance.
your most likely need to replace the crankshaft sensor and probably will take care of the 0336 and 0338 codes.
you then need to check your coolant level, if low fill and look for leaks, if not low, most likely replacing the thermostat will correct other two codes

2001 Impala LS 3.8 L stalling leaning towards crank sensor, how to test and how pricey?


Bill honestly if your not getting code PO38 something on the MIL light isn't on .I would look at the fuel supply air supply .
Every engine needs 3 things to run electrical spark you have that AIR supply and Fuel supply .
Fuel pumps tend to last 10 years in chevys but take the fuel filter off stick the line comeing from the tank into a plastic soda bottle turn the key to run this will start the fuel pump see how much fuel you get in 10 seconds then you can estamate gal per minuite this pump puts out 66 lbs pressure bolth ways feed and return .
Off hand don't know the spec for fuel flow but its high you should get a lot fast .Its fuel

My 1994 El Dorado is giving diagnostic codes PO38 (open IAT sensor)and PO71 (intermittent MAP). Not sure what these mean and/or if these are critical issues that need immediate attention. Please advise


IAT is: Intake air Temperature sensor.
MAP is: Manifold Absolute Pressure sensor. This one seems more important than the air temp.

They come together as one device.
Try www.Autozone.com for more advise.

Hope this helps.

2009 Ford Fusion SE 2.3L error codes P0491 and P0410. What are these and what steps do I need to take to fix them. Is there any diagrams or can someone specifically tell me the steps and places to look to...


Both of those codes refer to a problem with the secondary air system (air pump). The P0491 refers specifically to bank 1. Both codes are generic in nature and don't tell you anything specific about the problem so the whole system has to be troubleshooted. Look for damaged hoses or vacuum lines off for starters.
