  11 No crank reference signal detected during engine cranking. Intermittent
loss of either camshaft or crankshaft position sensor. CKP sensor target
windows have too much variation.
  12 Direct battery input to PCM was disconnected within the last 50 Key-on
cycles.
  13 No difference recognized between the engine MAP reading and the
barometric (atmosphere) pressure reading from start-up.
  14 MAP sensor input above or below acceptable voltage. 5 volt output to
MAP sensor open.
  15 No vehicle speed sensor signal detected during road load conditions.
  17 Engine did not reach operating temperature within acceptable limits.
Engine does not reach 20: F. within 5 minutes with a vehicle speed signal.
  21 Upstream oxygen sensor response slower than minimum required switching
frequency. Upstream oxygen sensor heating element circuit malfunction.
Downstream oxygen sensor heating element circuit malfunction. Downstream
oxygen sensor input voltage maintained above the normal operating range.
Oxygen sensor voltage too low, tested after cold start. (Upstream or
Downstream) Left oxygen sensor input voltage maintained above the normal
operating temperature.
  22 Engine coolant temperature sensor above or below acceptable voltage.
  23 Intake air temperature sensor input above or below acceptable voltage.
  24 Throttle position sensor input above or below acceptable voltage. TPS
signal does not correlate to MAP sensor.
  25 A shorted or open condition detected in one or more of the idle air
control motor circuits. Actual idle speed does not equal target idle speed.
  27 Injector #3, and/or 4, and/or 5, and/or 6 output driver does not
respond properly to the control signal.
  31 An open or shorted condition detected in the A/C clutch relay circuit.
Insufficient or excessive vapor flow detected during evaporative emission
system operation.
  33 An open or shorted condition detected in the duty cycle purge solenoid
circuit.
  34 An open or shorted condition detected in the Speed Control vacuum or
vent solenoid circuits. Speed control switch input below the minimum
acceptable voltage.
  37 Relationship between engine speed and vehicle speed indicates no torque
converter clutch engagement. An open or shorted condition detected in the
torque converter part throttle unlock solenoid control circuit. Incorrect
input state detected for the Park/Neutral switch. Auto only.
  41 An open or shorted condition in the generator field control circuit.
  42 An open or shorted condition detected in the auto shutdown relay
circuit. An open condition detected in the ASD relay output circuit. An open
or shorted condition detected in the fuel pump relay control circuit. An
open circuit between PCM and fuel gauge sending unit. Circuit shorted to
voltage between PCM and fuel gauge sending unit. No movement of fuel level
sender detected.
  43 Peak primary circuit current not achieved with maximum dwell time.
Misfire detected in one or more cylinders 1 thru 6. (4 and 6 cyls.)
  44 Battery temperature sensor in voltage above or below acceptable range.
  46 Battery voltage sense input above target charging voltage during engine
operation.
  47 Battery voltage sense input below target charging during engine
operation. Also, no significant change detected in battery voltage during
active test of generator output circuit.
  51 A lean air/fuel mixture has been indicated by an abnormally rich
correction factor.
  52 A rich air/fuel mixture has been indicated by an abnormally rich
correction factor.
  53 PCM Internal fault condition detected.
  54 No camshaft signal detected during engine cranking.
  55 Completion of fault code display on Check Engine lamp.
  63 Unsuccessful attempt to write to an EEPROM location by the PCM.
  64 Catalyst efficiency below required level. (Same as code 72)
  65 Power steering high pressure seen at high speed. (2.5L only)
  72 Catalyst efficiency below required level. (Same as code 64)
  77 Malfunction detected with poser feed to speed control servo solenoids.
