stevenM Posted July 25, 2005 Author Report Share Posted July 25, 2005 The car was not running. The PCM parameters are as follows. PD01=5.4 PD33=.28 PD78=0 PD02=82 PD34=0 PD78=0 PD03=82 PD35=0 PD79=0 PD04=28 PD36=128 PD80=.000 PD05=31 PD37=128 PD81=.0 PD07=51 PD38=128 PD82=.000 PD08=8 PD39=128 PD83=2 PD09=2.456 PD40=.00 PD84=64 PD10=.0 PD41=0 PD97=1306 PD11=0 PD42=0 PD98=2 Pd12=0 PD70=21 PD99=1106 PD13=0 PD71=111 PD15=12.0 PD72=0 PD16=0000 PD73=0 PD17=0010 PD74=.000 PD30=.0 PD75=1.035 PD31=.0 PD76=4.000 PD32=.00 PD77=28 I thought I would list all the codes. Is there a site that list them and the normal operating range? Thank you in advance. The 'normal' range would depend on the operating conditions. The service manual suggests minimum/maximum acceptable values, but some interpretation is needed. The MAP reading (PD02) prior to start-up indicates the barometric pressure (PD03). I suppose 82 kPa would be acceptable for Denver, but closer to sea level, I'd expect 99-103 kPa. I wonder why PD32 (front O2 sensor voltage) is at 0.00 volts; PD33 (rear O2 voltage) is more reasonable. At key-on, the voltage would start at the reference (0.45 V) then drop gradually as the heating element warms it up. See what PD32 reports while running, and compare it to PD33. PD98=2 means there have been two ignition cycle events since the last trouble code was set, or the battery was disconnected recently. I will get out in the morning and run the engine, and see if the parameters change. If the 02 sensore is not working that may be my problem. I will have to trace the wires. Yes, I have been disconnecting the battery hoping to reset what ever was wrong. I would like to thank KevinW for all his efforts. Link to comment Share on other sites More sharing options...
