Ck. engine lt. code 1676 - 2004 Honda Accord

Warm Up Catalyst Efficiency Bank 1 Below Threshold If you ran you car for a long period with it missing, then you probably damaged your catalytic converter.

I do not have the code but if you have a diesel the check that the glo-plugs are working . Check fuse to the relay

You need a repair shop to properly diagnose why you have any codes

You can Google all your asking-- but certainly can not diagnose & repair
without experience

crank sensor /cam sensor corrolation codes meaning one was changed and the system wasn't relearned

This is for Evaporative Emmision Purge Solenoi Circuit.I would look for a broken wire going to this circuit.If you do not find any broken wires then the purge solenoid more than likely is faulty.

The check engine light will stay on until the problem is fixed or corrected. Scan the engine and get the trouble codes which will give you and idea of what is causing the problem. Auozone and some other part store will scan it for free.

u need 2 have someone with a high quality scanner ck. the history codes

P2088 Dodge ,That is a cam position actuator, Not a cam sensor, Cam actuator control the cam angle, If this is ****** or advanced you'll definetly get CK ENG LT 2032, 2032 is reporting the engine condition and CK engine light is on due to a logic check, The function check has been suspended and the ECM is reporting the logic which is the condition of the vehicle, The first code was correct, P2088 that is a function failure. If there is acces to a freeze frame it will show at what MPH the vehicle was going if it is less than 40mph you can be sure the cam actuator is not advancing. Leave 2032 alone trouble shoot P2088 that is the source

 Electronic control module (ECM) computer circuit problems - faulty programmable read-only memory (PROM). OR (Transmission) Input or output speed sensor - circuit problems. (Speed sensor signals do not agree with with selected gear range.) OR Torque converter clutch (TCC) - TCC is mechanically stuck on.
 Vehicle anti-theft system (VATS) problem. OR Transmission Temperature Sensor (TTS) - short circuit problem in sensor or wiring. OR Transmission fluid temperature high.

Yes. 1 is a bad O2 sensor and the other a mis-fire.

Best thing to do is a major tune up (replace plugs/wires/fuel filter/PCV valve/etc...) and also replace the Bad O2 sensor.

Running it like this can cause long term damage. Let alone you are losing gas milage as well.

Good luck.
