B18c1 engine Took it in to a mechanic and they couldn't pinpoint the problem. Both oxygen sensors ok fuel pressure ok MAP ok Fuel filter replaced No vacuum leaks found with carb spray Valve clearances to spec Last time with a previous integra i had code P0172 and it turned out to be the injectors. Yet I only found that out by replacing them. With this integra I can hear them all clicking and they read around 12ohms, I hope its not injectors again.
P0174 (bank 2)indicates that your air/fuel mixture is too lean. There is more air/oxygen than there is fuel. Typically lean running conditions can be caused by vacuum leaks, insufficient flow/pressuure from fuel pump, fuel line clogged or leaking, fuel pressure regulator stuck open, fuel filter clogged, fuel injectors clogged, gasoline quality (poor), bad primary oxygen sensor, valve clearances and exhaust leak. I would start out with the easiest possible cause: vacuum leaks.
I would check ignition timing.
Did they bleed the air out of the system?
I had the same symptoms on my car, turned out to be warped rotors. You can remove them and have them resurfaced or you can purchase new ones. Also if your pads are beginning to screech or indicate that it is time to change them I would do so as well. Usually your break piston presses against the pad and the pad stays consistently close to the rotor, I am not sure by "caliper is not disengaged"
Leaking refrigerant into the atmosphere can be illegal depending on local laws and regulations. Not to mention that if you inhale refrigerant it can also be dangerous to your health. Upon opening the a/c lines moisture enters and if not evacuated and correct amount of "pull" is used on the system there can be premature failure in the a/c compressor which will be an expensive part to replace.
Check for vacuum leaks if your idle is surging erratically.
Have you checked to see if there are any shorts or opens in the wiring going to the cooling fans and engine coolant temperature sensor? Also a faulty cooling fan relay can be the culprit These can be causes for these two codes p0481=cooling fan 2 control circuit p0118=engine coolant temperature sensor high input
P0108=Map/Baro sensor high input I would check to see if there are any vacuum leaks and the order of the spark plug wires. This code can also be brought on when there is a short in the wiring to the sensor as well as a vacuum leak Good luck
This is indicating that your ignition timing is out of spec. It should tell you somewhere in the engine bay, usually on the underside of the hood what the correct ignition timing should be. On my car timing can be slightly advanced or retarded by adjusting the distributor im not sure how its done on an impala. Depending how advanced the timing may be you may be able to easily correct it by adjusting your distributor yet if this was caused by a slipping timing belt your going to have to re-align your cams and crank pulley.
It might not be due to a lack of coolant, rather it could be a failing cooling fan engine or a thermostat stuck closed. If either of these two things begin to fail they can cause overheating. From my experience you can test the cooling fan by removing the cooling fan relay and with a jumper wire testing to see if the fan kicks on-if not this is your problem. For the thermostat, you would have to remove it and test it in a bowl of hot water making sure it reaches proper operating temperature to see if the thermostat opens. If for example your thermostat is supposed to open at 170F and it does not when testing then this is your problem.
I have a b18c swap in a honda civic, this swap is ref'd and all i need is a smog check to register it yet the cel light wont go away. I have replaced; fuel filter both oxygen sensor 1 and 2 cap and rotor i borrowed a scanner and the manifold absolute pressure sensor reading averages between 7.4-8.9 the throttle position sensor is 9.4% at idle engine coolant temperature sensor ranges up to 184F and then the fan kicks on intake air temperature sensor ranges between 60F(idle)-110F Also i had the valve clearances checked and they were fine I inspected the injectors and resistance is 12.2-12.3 OHM's Also this car has a fuel pressure gauge on the fuel filter, and it reads normal (51psi @ idle) Thank you
