Turn Signal Lamps
The TSIG/HAZ fuse in the rear fuse block supplies battery positive voltage to the flasher module. The module is part of the hazard switch assembly. The flasher module has ground at G201. The turn signal lamps may only be activated with the ignition switch in the ON or START position. The IGN-1 fuse in the rear fuse block supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flows from the turn signal switch assembly to the flasher module. The flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, the switch contacts are close and the turn signal/hazard flasher module hazard input is grounded. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage in an on and off flashing pattern to all the turn signal lamps. This also activates both turn signal indicators. When a THEFT is occurring, the DIM grounds the turn signal/hazard flasher module hazard input. The left turn signals have ground at G401 and at G402. The right turn signals have ground at G401.
Turn Signal Lamps
Ignition positive voltage from the HAZT/SIG fuse 15 in the instrument panel fuse block is supplied to the hazard warning switch. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. When the turn signal switch is placed in either the left or right position, the flasher module sends an ON/OFF voltage to the turn signal switch assembly. For the rear turn lamps, battery voltage is applied directly to either the left or right turn signal lamps. The ground for the rear turn lamps is supplied from G401. For the front turn lamps, battery positive voltage is applied from the turn signal switch to the instrument panel electrical center. From the instrument panel fuse block, battery positive voltage is applied to the instrument cluster (IC) indicators and to the normally-open switched side of either the DRL L or DRL R relay, depending on the turn signal switch position. Battery positive voltage is then applied to either the left or right turn signal lamps. The front turn signals are grounded at G102.
For the hazard lamps, voltage is applied from the STP HAZ fuse 8 to the hazard warning switch. When the hazard switch is pressed, all the turn signal lamps will flash, including both IPC turn signal indicators. The hazard warning switch is grounded at G201.
Your best bet , take it to a qualified repair shop.
{: ) The engine oil pressure sensor is on the left rear side of the engine block. Remove first the intake manifold sight shield (cover). The 3 wires all go to the powertrain control module (PCM).
Black = low reference ; Gray = 5v reference ; Tan/White = oil pressure signal.
On the other hand, the oil level sensor has two wires; Black/White = ground (G103); Brown = oil level signal going to the PCM. See sample diagram below:
The PCM monitors the input signals coming from these two sensors, and it will communicate to the cluster (IPC) through Class2 serial data line. The IPC will then indicate the corresponding values on the pressure gauge and will also indicate a warning lamp or message when necessary.
Some of th intermitent problems with lights can be traced to bad ground connection since flasher bulbs draw quite a bit of current. Some cars use the car bodywork as the ground connection. If the rear lamp flashes faster than normal when the front one does not you have a bad connection. Check the bulb holder and the ground connection.
The tiburon turn signals are controlled by a bcm (body control module) The bcm controls the ground to the signals. These always go bad and cause the signal to stick on or just not work. hope i was a help.
Sounds like a bad earth/ground - remove the lense covers and clean the bulb panel contacts also check the brake and indicator switches for rust on the contacts, Hope this helps
