[b] If the resistance measurement is less than or equal to 10,000 , a short exists between
#110 and #109 or where less than 10,000
resistance was read. Repair the short.
Refer to section 41.3.15.

Open Timing Reference Sensor Line Check
Perform the following steps to check the open TRS line.
1. Disconnect the TRS connector.
2. Install a jumper wire between sockets A and B of the TRS harness connector.
3. Measure resistance between sockets T1 and T2 on the engine harness connector.
[a] If the resistance measurement is less than or equal to 5 , refer to section 41.3.4.
[b] If the resistance measurement is greater than 5 , or open, the signal line #110 or
return line #109 is open. Repair the open. Refer to section 41.3.15.
41.3.4
Check Timing Reference Sensor Resistance
Perform the following steps to check TRS resistance.
1. Measure resistance of TRS across sensor connector pins A and B. See Figure 41-4.
[a] If the resistance measurement is greater than 200 , refer to section 41.3.12.
[b] If the resistance measurement is less than 100 , refer to section 41.3.12.
