- Fri Mar 20, 2009 7:33 pm #104636 okay so i swap a d16z6 into the cx chassis, when i turn on the car it sounded werid. theres also was cel code 1 and code 20, any one know whats the problem to fix it??

- Sat Mar 21, 2009 3:25 am #104730 Code 1 is o2 sensor, i think.
Code 20 is electric load detector, i think.
other than that, more needs to be described. "it sounded weird" doesnt say much

- Sat Mar 21, 2009 4:07 am #104749 you went from a 1 wire to a 4 wire on the o2 sensor, I'd double check your wiring.

The ELD can be a PITA to diagnose... I'd check your wiring and fuse boxes to start with. Be sure all your fuses are good and fit tight in the slot. from there, you can try swapping the underhood fuse box to see if it goes away. if it is still there then you've got a problem in the wiring some place.

Do Not PM me your technical questions. Post them in the forum!

The Malfunction Indicator Lamp (MIL) indicates Diagnostic Trouble Code (DTC) 1: A problem in
the Heated Oxygen Sensor (HO2S) circuit.
The heated oxygen sensor detects the oxygen content in the exhaust gas and signals the ECM. In operation, the ECM
receives the signals from the sensor and varies the duration during which fuel is injected. The heated oxygen sensor
has an internal heater. The heater stabilizes the sensor's output. The heated oxygen sensor is installed in the exhaust
manifold.

- Sun Mar 22, 2009 3:47 pm #104938 The Malfunction Indicator Lamp (MIL) indicates Diagnostic Trouble Code (DTC) 20: A problem in
the Electrical Load Detector (ELD) circuit.
With service check connector
jumped (see page 11-22), code
20 is indicated.
Do the ECM Reset procedure (see
page 11-23).
Start engine and keep engine
speed at idle.
Turn on headlights.
Does the MIL indicate code 20?
Intermittent failure, system is OK
at this time (test drive may be
necessary).
Check for poor connections or
loose wires at C202 (ELD) and ecu.
