0038 is 1/2 heater curcuit heater high, what does this mean
basically it means the 02 sensor has some issues. it could be something as simple as frayed wiring or a deattached wire from impact. should be an easy fix. heres the manual direction for testing. or just get under there and check the wire paths.:grin:

P0038-O2 SENSOR 1/2 HEATER CIRCUIT HIGH
For a complete wiring diagram Refer to Section 8W.
9 - 24 ENGINE ELECTRICAL DIAGNOSTICS LX
² When Monitored:
Battery voltage above 10.6 volts, ASD is powered up, and O2 heater is off.
² Set Condition:
Desired state does not equal Actual state. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes
(K299) O2 1/2 HEATER CONTROL CIRCUIT OPEN
(Z902) O2 1/2 HEATER GROUND CIRCUIT OPEN
(K299) O2 SENSOR 1/2 HEATER CONTROL SHORTED TO BATTERY VOLTAGE
O2 SENSOR
PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1. ACTIVE DTC
Ignition on, engine not running.
With a scan tool, read DTCs.
Is the DTC active at this time?
Yes >> Go To 2
No >> Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2. O2 HEATER ELEMENT
Turn the ignition off.
NOTE: Allow the O2 Sensor to cool down to room temperature.
Disconnect the 1/2 O2 Sensor harness connector.
Measure the resistance across the O2 Sensor Heater element, between the Heater Control terminal and the Heater
ground terminal at the component.
NOTE: O2 Heater Element resistance values should be measured at 70°F (21.1°C). The resistance value will
vary with different temperature values.
Is the O2 Sensor Heater Element resistance between 2.0 and 30.0 ohms?
Yes >> Go To 3
No >> Replace the O2 Sensor.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
LX ENGINE ELECTRICAL DIAGNOSTICS 9 - 25
3. (K299) O2 1/2 HEATER CONTROL CIRCUIT
Ignition on, engine not running.
With a scan tool, actuate the O2 1/2 Heater Test with the O2 Sensor
harness connector still disconnected.
Using a 12-volt test light connected to ground, probe the (K299) O2 1/2
Heater Control circuit in the O2 Sensor harness connector.
Does the test light illuminate brightly and flash on and off during
the actuation?
Yes >> Go To 4
No >> Go To 5
4. (Z902) O2 HEATER GROUND CIRCUIT OPEN
Turn the ignition off.
Measure the resistance between an engine ground and the (Z902) O2
1/2 Heater ground circuit in the O2 Sensor harness connector.
Is the resistance below 5.0 ohms?
Yes >> Replace the O2 Sensor.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No >> Repair the open in the (Z902) O2 1/2 Heater ground circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
5. (K299) O2 1/2 HEATER CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE
Turn the ignition off.
Disconnect the PCM harness connectors.
Ignition on, engine not running.
Measure the voltage on the (K299) O2 1/2 Heater Control circuit in the
O2 Sensor harness connector.
Does the voltmeter indicate any voltage present?
Yes >> Repair the short to battery voltage in the (K299) O2 1/2
Heater Control circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No >> Go To 6
9 - 26 ENGINE ELECTRICAL DIAGNOSTICS LX
6. (K299) O2 1/2 HEATER CONTROL CIRCUIT OPEN
Turn the ignition off.
CAUTION: Do not probe the PCM harness connectors. Probing the
PCM harness connectors will damage the PCM terminals resulting
in poor terminal to pin connection. Install Miller Special Tool #8815
to perform diagnosis.
Measure the resistance of the (K299) O2 1/2 Heater Control circuit from
the O2 Sensor harness connector to the appropriate terminal of special
tool #8815.
Is the resistance below 5.0 ohms?
Yes >> Go To 7
No >> Repair the open in the (K299) O2 1/2 Heater Control circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
7. PCM
NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal
push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and
Ground circuits.
Were there any problems found?
Yes >> Repair as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No >> Replace and program the Powertrain Control Module per Service Information.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

I believe what I hit to be a deer, it was already dead. Oh my, what a horrible sound. I was under the car this morning and removed engine cover. that was in about 3 pieces. With further investigation found the down range o2 sensor on the right side was unplugged. I plugged it back in and re-hung it in its place and secured it with a zip tie due to the fact that the plastic hanger it once was secured with from the factory was no longer there. I know need an engine cover. If that cover was not there i'll almost bet there would have been more damage. damage to the steering rack and other lines in the bottom of the engine bay. The battery was re-connected and car started, check engine light extinguished and car is running as it did before. I need to replace that engine cover. where can i get one and for how much?
