i have a 1989 dodge daytona 2.2 turbo with a very rich a/f. the codes are 12,15,52,55. i've got over $4000 into the motor almost everything is new. it starts great! idels great. yet if you try to drive her she gives me a cloud of smoke and a under powered excel. my boost gage reads no boost and a strong vac. yet i pull off the intake pipe and i feel a little wind. this is my first turbo car. my experence is mostly with my big block 73 duster. so help me please get this basket case back on the road bulling imports!!!!!!!!!

 

See if your map sensor is hooked up

 

the map is new along with all most everything else and is connected tested and working. thanks!

 

CODE 52
Description: Oxygen sensor output indicates rich too long
Power loss light: Off
Limp-in mode: Engine allowed to run rich, but prevented from running lean
Possible Causes Bad oxygen sensor - Replace the sensor which is located on the turbo housing near the down pipe (for turbo) or on the down pipe near the exhaust manifold. Bad connection or wiring - Check the wiring and connections between the sensor and the logic module (or SMEC). Clean and regrease any corroded connectors with dielectric grease and repair any shorts. Look for melted wire insulation near the exhaust manifold. A shorted connection to any positive source will cause this fault code. High fuel rail pressure - See the Diagnosing Your Fuel System page.
Diagnostic Method Trigger Parameters - In closed-loop
- Sensor output indicates rich for more than 715 seconds (11 minutes, 55 seconds) Results If Component Fails A fault code 52 is stored, the circuit stays in closed-loop, and the logic module will still monitor the oxygen sensor signal. If the condition persists for four times what it took to set the code, the logic module will allow the engine to run rich, but prevent it from running lean.
