Code P1290 on an Isuzu Rodeo typically indicates an issue with the engine control module (ECM) related to the throttle position sensor (TPS) or the intake air temperature sensor. This code can suggest that the ECM is not receiving the expected signals from these sensors, which may affect engine performance. It's advisable to check the wiring and connections for any damage or corrosion, and to test the sensors for proper functionality. If necessary, replacing the faulty sensor or repairing the wiring can help resolve the issue.

Trouble code P0463 means:Fuel level sensor circuit high input
Trouble code P0461 means:Fuel level sensor circuit range/performance
Trouble code P0442 means: Evaporative Emission System Leak Detected (small leak)
Trouble code P0507 means:Idle control system RPM higher than expected
oxygen sensor
Not a valid code. If it's P0134 the it would be oxygen sensor bank 1 sensor 1, no activity detected.

it is low coolant temperature, could be the thermostat could be the sensor for coolant temperature.
The check engine light on a 1997 Isuzu Rodeo could mean a failure in the ignition system has been detected or one of the cylinders has misfired. Hooking an OBDII code reader to the vehicle can determine the exact cause.
Well I just checked about 6 sites that list Isuzu specific obd2 codes. Problem is, not a single one of them list that code. Are you sure it's the right code? If it is, you're probably going to have to ask a dealer or mechanic. If you mean P0128 that's a thermostat insufficicent temp and it req's a t-stat
