Reatta code 43 check engine light goes off when hard decelleration

cam sensor codes

Have your intake check your intake manifold gaskets maybe spray some Carb cleaner around it while the engine is running if the idle goes up you have a leaky intake manifold gasket also clean your aic valve

Check & inspect bulbs and sockets on the right side front and rear. Also check the bulb and socket you just replaced.

Check engine light usually means some failure in emissions control
system. Kia will have to hook up and get diagnostic code or codes.

You first need to get it scanned to find out the error code. There are many possibilities! Most auto parts stores will do this for free, and then you go from there.

if is doing it thru the carb then the fuel mixture is too lean, if is in the exhaust (also called after-fire) the fuel mixture too rich.

OBD Code 12 - No Distributor Reference Pulse (Diagnostic Test Active) The Engine Control Module-ECM uses the distributor reference pulse to calculate the engine speed. On newer engines, the Crank Shaft Position Sensor performs this function.

Symptoms:

• When flashing the Check Engine Light to read codes, code 12 will always display first, indicating the diagnostic system is active
  
• The engine will not run with a "hard" code 12 set
  

Common Problems:

• Chances are you will never need to diagnose a code 12. Rather, the problem would be a crank, no-start condition.
• If code 12 does not flash, that would indicate a communication problem with the ECM.
• Code 12 does not show when reading codes with a scan tool. If there is a communication problem, the scan tool will let you know.

OBD Code 46 - Pass-Key II System Error - Circuit out of Frequency Range The ECM receives a signal from the Pass-Key module. When the correct signal is received, the ECM will allow the engine to start and run. Please review the RepairPal article on the GM Pass-Key Anti-theft systems for more information.

Symptoms:

• Engine may not start

Common Problems:

• Faulty ignition lock cylinder

OBD Code 43 - Knock Sensor error The ECM receives a signal from the Knock Sensor based on the amount of engine ping detected. The ECM uses information from this sensor to help calculate fuel delivery and spark timing.

Symptoms:

• Engine ping
• Lack of power

Common Problems:

• Faulty Knock sensor
• Poor connection at Knock sensor

OBD Code 55 - End Test.


Hope ehit help (remember comment and rated this).

hook up a timing light; crank over the engine; check when the problem occurs... if the light goes on = good spark
light off= bad ignition
to check fuel use a pressure gauge 40/60psi=good
below 40psi check/replace fuel filters/pump
don't use the screwdriver-in-the-plugwire-to-ground trick!!!
don't suspect the computers/electronics as; the car starts sometimes.
hope this helps!

think electrical 1st -the weakest link-bet u havnt had tuneup since yr 1000-inspect plug wires for wear n take off dist cap n look inside-scarry!--of course chec fuel system also in gas tank area

I've been having an issue with my Reatta not starting too, and believe it to be a fuel or fuel mix issue. I replaced the fuel pump last weekend thinking it might have improved things, but it didn't. When I go to start it and turn the key to ignition, it just cranks. When I turn the key to 'on' position and let it sit for 5-10 seconds before cranking it will sometimes start - so I think it is an issue with feeding the engine fuel. This will be my project for the weekend - seeing if it is a fuel regulator issue or something else. I found some info on the buick reatta web sites that might help me determine the codes and hopefully determine the issue. Oh yea, I also replaced the oxygen sensor too thinking that might be causing part of the issue (but you can't keep replacing parts to find the issue to expensive!). I'll try to follow up with this site if I find the issue.
