Nissan DTC P1140 - Intake Valve Timing Control Position Sensor (Bank 1)

Check the passenger side Intake Valve Timing Control Position (IVTCP) sensor for 12 volts on the Black/White wire. Check the IVTCP sensor for a good ground on the Black wire.

It should produce a square wave signal of around 8 volts. Check the pattern of the right side sensor and if unsure of the pattern, compare it to the left bank sensor.

Potential Causes: IVTCP Sensor
Wiring - IVTCP sensor wiring/connection.

Hope helps.

I took my car to have it checked at Autozone. The results were OEM Number to Cross: P0102. What is wrong with my car?

P0102 refers to the MAF (Mass Air Flow) sensor. It may be dirty, faulty, or have a bad connection. Possible remedies are:

  • Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
  • Inspect for any air leaks near the MAF sensor.
  • Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
  • Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
  • Replace the MAF sensor.

Where is the knock sensor located on a 2005 gmc sierra 1500 4x4 5.3 L

Do not replace with Autozone knock sensors unless you feel like doing the job twice as I found out the hard way. I replaced mine and a week later the check engine light came back on. Went to the dealer and was told they have seen this problem many times before and to use oem replacement parts only. The two sensors and harness ran me about $230 from the dealer but no more engine light and no more sputtering. Hopefully I can return them to Autozone as soon as I find the receipts.

1990 Jeep Cherokee Intermittent Starting after short runs

I think you are needing a starter relay. Part#33003934 at $50.30 from the dealer. Try getting an aftermarket place like autozone or pepboys to cross the oem number.
